H7 or H11? Choosing the Right Headlight Bulb for You

Swapping out your headlight bulbs shouldn’t be confusing, but the reality is that with so many bulb types and sizes available, it’s easy to pick the wrong one. Among the most commonly used bulbs are H11 and H7 bulbs. Understanding how they are different from each other can help you ensure that you’re installing the right fit for your vehicle’s lighting setup. Here’s a simple guide to help you decide between the two.

What is an H7 bulb?

H7 bulbs are single-filament lights known for their sharp, focused beam. LED versions of H7 bulbs have become more common than halogen types because they offer greater brightness and better energy efficiency. Many modern vehicles use H7 bulbs in their headlight systems because they provide strong, direct illumination without excessive glare, making night driving safer and more comfortable.

What should you know about H11 bulbs?

H11 bulbs are also single-filament, but they’re typically used for low beams and fog lights. Their beam pattern is wider and less focused to help improve visibility in poor weather conditions like rain, fog, or snow. Drivers often choose H11 bulbs for the way they enhance peripheral lighting—especially along the edges of the road.

How do H7 and H11 bulbs compare?

• Ease of installation - Both H7 and H11 bulbs are relatively simple to install, but H7 bulbs tend to be more straightforward. The H7 plug is exposed, making it easy to identify and connect. H11 bulbs often require a little more care due to their more compact housing and tucked-in connector.
• Brightness - H7s are generally brighter than H11 bulbs, making them a better choice when driving on rural or unlit roads. H11 bulbs still deliver good brightness, but they’re tailored more for low beams and fog lights.
• Lifespan - Both bulbs last long, but their longevity depends on how often you use them. Since high beams are typically used less than low beams, H7s may last longer in everyday use.
• Beam pattern - H7s provide a tight, focused beam that lets you see as far ahead as possible without scattering light. H11 bulbs, on the other hand, spread light more widely, making them better suited for low beams or fog lights, where lighting the sides of the road matters more.
