Fog can turn even familiar roads into a blur. That’s why knowing when to use your fog lights is essential. When used correctly, car LED bulbs for fog lights help you see well and keep you safe during low-visibility conditions. But not every situation calls for them; in fact, using them when visibility is good could dazzle other drivers and land you with a fine.

When should you turn on fog lights in the UK?

When visibility drops below 100 metres (roughly the length of a football pitch) — that’s when you should turn on your car LED bulbs for fog lights. At this level, the fog is thick enough to make it difficult for you to see vehicles ahead or behind.

Don’t forget to use your regular headlights as well. Just avoid using high beams, as they reflect off the fog and reduce visibility even more.

Besides endangering yourself and others, not using your fog lights when you should could also risk invalidating your car insurance if you’re involved in an accident.

Is it illegal to use fog lights when it’s not foggy?

Yes. Fog lights are meant only for foggy conditions when visibility drops below 100 metres — a rule that comes directly from the Highway Code (Rule 226).

Additionally, the Road Vehicles Lighting Regulations 1989 says it’s an offence to use fog lights when visibility is clear, as they can dazzle other road users. You shouldn’t use them in drizzle or light rain, or even mist that doesn’t significantly limit your view of the road.

If you’re caught using fog lights unnecessarily, you could face a fine from the police. Once visibility improves or the fog clears, make sure to switch your fog lights off to stay compliant and to show courtesy to other drivers.

Best LED fog light bulbs for UK weather

Car LED bulbs are the most practical upgrade for fog lights, especially if you want outstanding brightness and energy efficiency without compromising reliability. With longer lifespans and cooler operating temperatures, LED fog lights deliver consistent visibility through foggy conditions and heavy rain, making them ideal for unpredictable weather in the UK.

Many modern car LED bulbs for fog lights also allow for customisable colour temperatures and adjustable beam patterns, giving you flexibility for different driving environments.

Driving on icy or snow-covered roads can be challenging — the slippery surfaces and reduced visibility can make even short journeys quite stressful. That said, having the right headlights improves your ability to spot hazards and react quickly on winter roads. Why not upgrade to a brighter and more reliable option such as the headlight LED bulbs?

At HIDS DIRECT, we supply high-performance LED headlight bulbs designed for both dipped and main beam setups. Each pair delivers crystal-clear 6500K white light and easy plug-and-play installation while ensuring full CANBUS compatibility. They’re perfect for winter conditions where every second of visibility matters.

Headlights are essential in low-visibility conditions

Rule 226 of the Highway Code requires you to use headlights when visibility drops below 100 metres (328 feet). You can also use your fog lights, but as Rule 236 reminds us, you must switch them off once visibility improves.

What makes LED headlights great for winter driving?

See clearly with brighter light - A headlight LED bulb emits a clean white light that’s significantly brighter than the yellowish glow of halogen bulbs, making it easy to spot road markings and hazards, even in foggy or snow conditions. Driving on dark, rural roads? LED bulbs will help you see clearly without straining your eyes.

Save energy and money - LED headlights consume less power without compromising high brightness, making them more efficient than halogen bulbs. This reduces the load on your car’s electrical system, leading to fuel savings in petrol and diesel vehicles. The savings may seem small per trip, but they add up significantly over time. Driving an EV? You can rest assured that the lights won’t eat your battery life within a few hours.

Least likely to fail in harsh weather - Unlike halogens that often need replacing every couple of years, a headlight LED bulb can last tens of thousands of hours — often as long as the car itself.

Colour temperature and fog performance - LED headlights that emit yellow or amber-toned beams are especially effective for foggy and snowy conditions. These colours reduce glare and cut through mist more effectively than bright white or blue tones, helping you see more clearly without dazzling other drivers.

Comparing LED vs. halogen performance in freezing conditions

Keep your headlights in good condition

Check that every headlight LED bulb on your car is clean and free of any snow and ice before heading out.

Are you worried about LED headlight bulbs generating very little heat? It’s a nice energy-efficient feature, but it can sometimes make snow and ice build up on the lens, reducing brightness.

Some advanced models, such as the D-Lumina LED Headlight Bulbs, include an integrated cooling fan to help disperse heat efficiently. Certain vehicles even feature built-in heating elements to prevent ice accumulation, but if yours doesn’t have one, it’s best to scrape away any frost or snow before setting off. Additionally, keep an eye on the headlights during your drive in heavy snowfall.

Are you planning to upgrade your car’s headlights? The first step is knowing what socket type your car uses, since each bulb is designed for a specific fit and purpose. (For example, an H1 bulb is a single-beam design used in high or low beam headlights.) If you pick the wrong type, the bulb will sit crooked or even fail to lock into the housing altogether.

Automotive bulbs (regulated under UN Regulation 37) are divided into three groups.

• Group 1 bulbs are approved for all vehicle lighting functions, including headlights and taillights.
• Group 2 bulbs cover the lights for signalling functions such as indicators and brake lights, while,
• Group 3 applies to smaller applications.

In this guide, we’re covering the socket types that are part of Group 1, from the H1 to the H11 bulb.

Identifying the bulb sockets

Headlight bulbs come in different socket types, and sockets are usually grouped by their base design and the number of locking tabs — which is why you’ll often see them listed as part of the H-series or D-series.

Even though LED headlights are becoming more popular, most cars still roll off the factory line with halogen bulbs. And within these, a few socket types dominate — in fact, H7 bulbs, H11 bulbs, and H1 bulbs together fit more than 98% of vehicles on the road. Less common types like the H3 socket are used in narrower applications such as fog lamps.

Let’s take a closer look at the main types:

H1 bulbs

With a single power plug, the H1 bulb is often used in high beams for both 12V and 24V vehicles. Some vehicles also use H1 bulbs in their low beam setup, making them versatile and widely compatible.

H7 bulbs

The H7 bulb has a two-pronged plug and a single-beam design, meaning one bulb is required for high beam and another for low beam. This type is frequently used as the low beam bulb in German and Korean vehicles, as well as Chinese and European cars.

While H4 and H7 bulbs may look similar, they differ in important ways, including base structure and lighting performance. So, it’s best to check for compatibility before replacing them.

H11 bulbs

The H11 bulb is a single-filament halogen bulb with an L-shaped base, making it common for low beams. Some vehicle manufacturers, such as Volkswagen and Kia, also use them for fog lights and daytime running lights.

Drivers sometimes assume that the H8 bulb is interchangeable with H9 and H11 bulbs because they have a similar shape. However, there are differences in their wattage and brightness, as well as application. An H11 bulb may work in a fog light application, but an H9 or H8 bulb may be better suited for specific brightness or power requirements.

H3 bulbs

Although it’s now less common, H3 bulbs are still found in some headlight systems and fog lamps. They require a dedicated socket that provides a secure connection to the electrical circuit. H3 sockets can handle vibrations and moisture well because of their durable, corrosion-resistant materials.

H8 bulbs

Many fog lights use the H8 bulb. Standard halogen versions typically have a service life of around 320 hours and consume about 35 watts of power. They’re not as common as H7 bulbs or the H11 bulb, but they support specific vehicle models that need dedicated fog lights.

Upgrading your car’s headlights with LEDs is one of the easiest ways to boost your visibility on dark highways and rural roads while giving your vehicle a modern look. But to get the most out of your new car headlight bulbs, you need to install them properly.

New to installing LED headlights? Let this guide walk you through the process, so you can complete the upgrade with confidence.

Why go for LED headlights?

Before getting into the installation process, it’s worth knowing why so many drivers are making the switch to LEDs:

• LED kits are easy to install, with plug-and-play options to further simplify and speed up the process.
• LEDs deliver stronger, more focused beams for safer night driving.
• Drivers love the sleek appearance that updates the look and feel of their cars.
• Many LED bulbs last up to 50,000 hours, far outlasting halogen options. This means fewer replacements down the road.
• LED car headlight bulbs consume less power, reducing the strain on your car’s electrical system.

Things you’ll need for a seamless installation

Gather the following before you start:

• Vehicle owner’s manual
• The right LED headlight bulbs that suit your vehicle’s make and model

How to install new LED headlight bulbs

Prepare to install the LED bulbs

Start by reviewing both your car’s manual and the instructions that came with your LED kit. They’ll tell you exactly how your headlight assembly is designed. Make sure your vehicle is turned off and the headlights are cool to the touch. Don’t forget to disconnect the battery before installing the car headlight bulbs.

Remove the old bulbs

1. Locate the headlight housing - Open the hood and find the back of the headlight assembly.
2. Remove the dust cover - If your car has one, twist it off to access the bulb.
3. Disconnect the wiring harness - Gently unplug the connector at the back of the bulb.
4. Remove the bulb - Twist the bulb counterclockwise and pull it out. Dispose of it properly.

Install the new bulbs

1. Inspect the LED car headlight bulbs - Make sure they’re the correct fit and free of damage.
2. Insert the LED bulb - Align it with the socket, push it in, and twist clockwise to secure.
3. Reconnect the wiring - Attach the wiring harness until you hear a click.
4. Replace the dust cover - If you have this, reinstall it to keep the assembly sealed.

Your comfort and safety on the road depend on the quality and type of headlights you use. If you want brighter light, you’ll find popular options like H11 LED and xenon bulbs, which are both known for delivering brighter light and longer lifespans.

New to the H11 bulb? In this blog, we’re exploring why it’s the widely used bulb size today and how to pick the right type!

Where to use an H11 bulb

Commonly used as low-beam headlights and foglights, H11 bulbs help keep you safe when driving at night or in poor weather conditions such as fog and snow.

Each H11 bulb technology has different benefits. Halogen bulbs are the cheapest but also the dimmest, with a shorter lifespan, while LED bulbs are the most efficient and capable of producing a crisp, bright beam instantly. They outlast both halogen and HID types, making them a safer and more reliable option. We also have HID (High-Intensity Discharge) bulbs that are brighter than halogens.

What are the types of H11 bulbs?

H11 bulbs come in three main types, and each one affects how you see the road — some burn brighter, others last longer.

• Halogen H11 bulbs - Halogen bulbs have been the standard for years because of their affordability and wide availability. They’re also easy to install. While they emit warm yellow light that’s easy on the eyes, they’re not the brightest around. Moreover, they use more power than modern bulbs, so expect them to burn out quickly.
• LED H11 bulbs - Drivers who want a bright and reliable H11 bulb choose LED bulbs because they use far less energy to create a clean white beam, so they last much longer than halogen and HIDs. They also light up instantly, improving both safety and the overall look of your vehicle. Although they cost more, their longevity and performance usually offset the investment.
• Xenon H11 bulbs - Brighter than halogens, Xenon or HID bulbs produce a sharp white or bluish light that’s excellent for nighttime driving. They just have a few drawbacks: they need a few seconds to reach full brightness, and installation can be more complex since they often require a ballast.

Which H11 bulb should you use?

Not all H11 bulbs perform the same way. Ultimately, your choice should depend on whether it’s affordability or brightness that matters more to you.

Halogen H11 bulbs are a great option for drivers who want a low-cost, plug-and-play solution with dependable but moderate light output. LED H11 bulbs are the best all-rounders that are bright and long-lasting, making them ideal for upgrading to a reliable, energy-efficient H11 bulb. If you prefer brighter, cooler light, HIDs are the way to go as long as you don’t mind the complex installation and the additional ballasts required.

Selecting the right H11 bulbs

With a balanced 55-watt output, the H11 bulb is easily a solid choice for low beams and fog lights.  But before you swap bulb types, we recommend double-checking the pin alignment and wattage. Additionally, check the application they’re designed for. All this will help you avoid electrical issues and ensure that your new bulbs can work without problems.

Driving at night or in poor weather can be stressful if your headlights aren’t doing their job. That’s why carmakers keep pushing headlight technology forward to give us better visibility and efficiency, without sacrificing style. Today’s vehicles typically use one of three systems — halogen, LED, or xenon bulbs — and each one lights the road in its own way. Thinking of upgrading your headlights? Here’s what you need to know.

Halogen bulbs – The reliable classic

Halogen bulbs have been the workhorse of automotive lighting for decades. Inside is a tungsten filament that glows when electrified, while halogen gas within the glass helps recycle the filament and extend the bulb’s life. This simple, proven design also gives halogen light its signature warm yellow beam.

Some enhanced versions of these bulbs even use xenon gas for a slight performance boost, but they’re still halogen at heart — not to be confused with true HID systems. Although affordable and easy to replace, halogen lights can feel outdated with their softer light compared to newer options like LED and xenon.

Xenon bulbs – Brighter with a modern edge

Xenon headlights (or HIDs) changed the game when they hit the market. They create an electric arc between electrodes inside a chamber filled with xenon gas and metallic salts instead of using a filament. The result is a powerful, bluish-white light that illuminates the road far better than halogens.

That intense light comes from the more complex hardware in Xenon lights.  Each bulb needs a ballast to deliver a massive initial voltage and keep the current stable. Some setups also have an individual igniter, while others integrate it directly into the xenon bulbs. With levelling motors to prevent glare and headlight washers to keep the lens clean, you’ve got a high-performance lighting system to help improve your safety on the road.

At HIDS-Direct, we stock OE HID xenon bulbs from industry leaders like Osram and MTEC. These brands set the benchmark for quality and brightness, so you know that you’re getting a bulb that delivers maximum clarity and reliability. We make it easy to find the perfect fit for your vehicle make and model, with options across colour temperatures and bulb types.

Thinking of switching to xenon headlights? Our full range of HID xenon conversion kits makes it easy to upgrade. Each kit is carefully selected for performance and durability, so you can trust that it will last and perform exactly as intended.

LED headlights - Efficiency meets precision

LED headlights are the newest standard in vehicle lighting, and they are quickly becoming a favourite. Instead of using heat or gas discharge, they rely on tiny semiconductor chips that produce light when powered. That makes them more efficient and cooler, using less energy to make the bulb last longer.

Beyond efficiency, LEDs also have a smart modular structure that makes them bright and highly adaptable. They have:

• An LED module for managing the chips that form your dipped or main beam with pinpoint accuracy.
• An indicator module that keeps turn signals sharp and clear.
• An AFS cornering module that shifts the beam with your steering for safer cornering.
• A DRL module that runs low-power daytime lights without glare, so other drivers can see you clearly.

Which bulbs are for you?

For the budget-conscious, halogen bulbs are still the most commonly used because they’re affordable and easy to replace. However, xenon bulbs may be the better option if you want brighter, more reliable light. Meanwhile, LEDs combine efficiency with high-tech features. The right choice depends on your driving needs and budget, but don’t forget to factor in the bulb’s compatibility with your car.

If it’s time to replace or upgrade, knowing what’s inside each system can help you make the right choice. And when you’re ready to buy, we’ll keep it simple. At HIDS-Direct, you’ll find quality LED, halogen, and Xenon bulbs from reputable manufacturers like Maruta and Philips. We even provide free next-day delivery on orders over £100, while our secure checkout and 30-day hassle-free return policy give you peace of mind when shopping for new headlights online.

Upgrading your lighting improves visibility and makes night driving safer. At HIDS-Direct, we stock a wide range of H1 headlight and fog light bulbs, whether you want brighter beams, a Xenon look, or a specific colour temperature. Not sure where to start? Here’s a simple guide to help you choose the right H1 bulb for your needs.

Check compatibility with your vehicle

Before anything else, make sure the bulb you’re considering is specifically made for H1 sockets and will fit properly in your car’s headlight housing. Your vehicle’s manual is a good place to confirm this, or you can use a trusted online bulb finder.

Also, always go for bulbs that meet the ECE certification standard. This means the H1 bulb is safe and legal for road use. It’s also smart to stick with recognised manufacturers like Maruta and Philips — brands known for reliable performance and long lifespan, as well as consistently bright, flicker-free lighting.

Explore colour and style options

Some drivers prefer a clean white light, while others want a bolder look. Maruta’s H1 55W 2900K Xenon Effect Upgrade Bulbs offer a warm, eye-catching glow. If you're after something brighter and cooler, the 12V White 5500K Xenon Gas-Filled and 7000K Cosmos Blue options deliver striking visuals while improving road visibility.

Brighten your night drives

If visibility at night is your top priority, the Osram Night Breaker range is worth a look. These bulbs offer up to 150% more brightness, which can make spotting road signs and pedestrians much easier when driving in the dark.

Prioritise long-lasting performance

Durability matters, especially if you don’t want frequent H1 bulb replacements. The Philips LongLife EcoVision bulbs are built to outlast standard alternatives, saving you time and hassle. Meanwhile, if you’re looking for something with a unique look, options like the Bolts Retro Yellow or Platinum HID Class bulbs offer dependable performance with a distinct finish.

Shop with confidence at HIDS-Direct

Upgrade your car’s lighting today here at HIDS-Direct and experience the difference.

Aside from lighting the road to help you see better, your headlights and taillights also make sure that other drivers can see you. That’s why they’re especially important when you’re driving through fog or any low-visibility condition. If you're replacing or upgrading your car LED light bulbs, make sure they’re bright enough to keep you safe while staying compliant with legal requirements.

How bright should headlights and taillights be?

High beams are designed to help you see farther down the road, but they’re not always the right choice. If another vehicle is within 200 metres (either coming toward you or driving ahead), switch to your low beams to avoid blinding other drivers.

Low beam headlights usually provide visibility between 30 and 45 metres (about 98 to 148 feet). This distance gives you a clear view of the road while keeping the light level safe for oncoming traffic.

If an approaching car doesn’t dim its high beams and the glare makes it hard to see, glance toward the left side of the road and stay within your lane. If needed, slow down or pull over briefly until your eyes adjust.

Why LED headlights improve visibility

A car LED light gives off a cleaner and whiter light compared to halogen bulbs. This colour temperature closely matches natural daylight, helping you spot signs, road markings, and potential hazards more easily, especially during long night drives. Because LED bulbs create a more focused beam, they also reduce glare for other drivers while improving what you can see in front of you.

Another benefit is beam control. LEDs are engineered to light the road precisely, and this added control means safer nighttime driving — for you and everyone around you.

Style and safety in one upgrade

At HIDS-Direct, we offer a wide selection of high-performance LED car lights that deliver both visibility and style. Whether you're upgrading for safety or want to give your vehicle a modern edge, we’ll help you find the perfect car LED light bulbs that meet both needs.

LED headlights are a popular pick for drivers who want bright and efficient lighting, and H7 bulbs are especially common for their strong output and long life. Thinking of upgrading your headlights? This quick guide explains how to choose the right H7 LED bulb and stay within the legal requirements.

Considerations when choosing an H7 LED bulb

There’s a wide selection of H7 bulbs available, and knowing what to prioritise can help narrow things down. Be sure to check:

Brightness (lumens)

 A higher lumen rating means better visibility. For example, the Osram Night Breaker 220 H7 delivers up to 220% more brightness with 1500 lumens and excellent beam focus for night driving.

Colour temperature

Bulbs rated around 6500K produce crisp white light that mimics daylight. This helps reduce eye strain and glare. If you’re looking for a stylish, cool-white output, consider the Maruta H7 55W 5500K Super White Xenon gas-filled bulbs.

Build quality

Stick with bulbs that are weatherproof and built to last. ECE certification is also essential — this ensures road legality in the UK and EU. A good example is the Philips RacingVision GT200 H7, which features a palladium-coated head and chrome base, as well as an anti-reflex coating — offering up to 80 metres of extra visibility.

Legal compliance

H7 bulbs are legal to use in the UK but ONLY if they meet brightness and beam pattern regulations, so always ensure that the bulbs you choose comply with the latest ECE standards.

Compatibility with your vehicle

Not every H7 bulb fits every car, so always double-check your vehicle manual. If you’re still unsure, contact us so we can offer expert guidance.

Installation ease

Many H7 LED headlights are designed to be direct replacements for halogen ones, so you won’t need specialised tools. For example, the Maruta H7 7000K Cosmos Blue Xenon Gas-Filled Upgrade Bulbs install easily and deliver noticeable visual upgrades without needing rewiring or adjustments.

Upgrade your headlights with HIDS-Direct

If one of your LED fog lights just gave out, you might be wondering if it’s okay to replace only that bulb or if it’s better to change both. Swapping out a single bulb sounds like a quick and budget-friendly fix, but that’s not always the best decision. In some cases, replacing both lights can save you time and help maintain a consistent look and performance.

Let’s break down when it makes sense to replace just one LED headlamp for your car and when changing both might be the more practical way to go.

The short answer: it depends

You can change just one fog light if your bulbs are fairly new and you have the exact model on hand. But if your current lights are older, replacing both at the same time helps you avoid mismatched brightness or a second burnout shortly after.

You can replace just one bulb if:

• Your current LED fog lights are less than a year old
• The other fog light still shines just as brightly and hasn’t changed colour
• You’re using the same brand and model for the replacement
• You’re working with a limited budget and need a temporary solution

That said, it’s better to replace both fog lights if:

• Your bulbs are over two years old
• You can’t find the exact replacement model
• The working bulb is starting to fade or shift in colour
• Buying a two-pack costs only slightly more than a single bulb
• You want balanced brightness and colour across both lights

Figure out why the fog light failed

LED fog lights are built for long-term use, but they’re not immune to issues. If one burns out earlier than expected, it helps to understand what went wrong before buying a new LED headlamp for your car. That way, you can avoid similar problems in the future.

Some common causes of early LED fog light failure include:

• Overheating and poor airflow
• Electrical problems like unstable voltage
• Vibration damage from rough roads
• Moisture entering the housing

Low-cost bulbs may also fail early or cause further electrical issues. To avoid that risk, stick with trusted, well-reviewed LED products.

Find the right replacement at HIDS-Direct

We make it easy to find reliable LED fog lights that fit your vehicle and last longer. Our bulbs are built to perform — and when you order from HIDS-Direct, you get great service, too.
