Why Choose Amber LED Bulbs?

Many vehicles use amber rear lighting for brake, tail or indicator functions. These premium LED bulbs maintain the correct amber appearance whilst delivering a significantly brighter and faster light output than conventional filament bulbs.

The instant illumination of LED technology helps improve reaction time for following drivers while providing a cleaner, more modern lighting performance.

Dual-Intensity Brake & Tail Light Operation

The P21/5W (380) is a dual-intensity bulb designed to perform two lighting functions from a single bulb.

These LED replacements provide a lower brightness for the tail light function and a much brighter output when the brake pedal is applied, closely replicating the operation of the original filament bulb whilst offering substantially improved brightness.

Bright OEM Amber LED Output

Unlike coloured filament bulbs that rely on tinted glass, these LED bulbs generate a rich amber light directly from the LED chips, producing a cleaner and more consistent colour output.

The result is excellent daytime visibility whilst maintaining the correct amber appearance required by many vehicle lighting systems.

Intelligent Super Canbus Technology

Each bulb incorporates an intelligent Super Canbus driver designed to minimise dashboard bulb warning messages, flickering, rapid flashing and electrical interference on many modern vehicles.

Whilst compatible with most Canbus systems, some vehicles with particularly sensitive bulb monitoring systems may still require an additional resistor or decoder.

Advanced Active Cooling

A built-in high-speed turbine cooling fan continuously removes heat from the LED chips, maintaining stable light output and helping maximise service life.

Combined with the CNC-machined aviation-grade aluminium housing, the bulbs remain cooler during prolonged operation, supporting reliable long-term performance.

360° LED Light Distribution

The multi-sided LED chip arrangement closely replicates the position of the original filament, producing an even light pattern throughout the reflector.

This helps maximise rear visibility whilst maintaining excellent light distribution across both tail and brake light functions.

Ideal Applications

• Brake Lights
• Tail Lights
• Rear Position Lights
• Parking Lights (vehicle dependent)
• Any compatible application requiring a P21/5W (380) bulb
• Any compatible application requiring a BAY15D dual-contact base

Technical Specifications

P21/5W (380) Compatibility

P21/5W and 380 are common designations for the same dual-filament bulb type. These bulbs utilise a BAY15D dual-contact base with locating pins positioned at different heights.

Please compare your existing bulb before ordering as similar-looking bases such as BA15D, BA15S and BAZ15D are not interchangeable.

Frequently Asked Questions

Will these P21/5W amber LED bulbs fit my vehicle?

These bulbs are designed for vehicles that use a P21/5W (380) bulb with a BAY15D dual-contact base. Please remove and inspect your existing bulb, check your vehicle handbook or compare the base before ordering.

Are P21/5W and 380 the same bulb type?

Yes. P21/5W and 380 are commonly used references for the same dual-intensity automotive bulb type. They normally use a BAY15D base with two electrical contacts and locating pins positioned at different heights.

Do these bulbs provide two brightness levels?

Yes. These are dual-intensity LED bulbs. They provide a lower output for the tail or rear position light function and a brighter output for the brake light or secondary high-output function.

Can these bulbs be used as indicators?

They may be suitable for certain vehicles that use a dual-intensity amber P21/5W bulb for combined lighting functions. However, most standard indicator applications use a single-intensity bulb, so please check the original bulb type and lamp configuration before ordering.

What colour light do these bulbs produce?

These bulbs produce a strong, rich amber light directly from the LED chips. The colour is designed to provide clear visibility without relying on tinted glass.

Are these bulbs Canbus compatible?

Yes. Each bulb includes built-in Super Canbus electronics designed to reduce dashboard bulb warnings, flickering, rapid flashing and shut-off issues on many modern vehicles. Some vehicles with highly sensitive bulb-monitoring systems may still require an additional resistor or decoder.

What is the difference between BAY15D and BAZ15D?

A BAY15D bulb has two electrical contacts and locating pins positioned at different heights. A BAZ15D bulb uses a different pin arrangement. Although the bases can appear similar, they are not interchangeable.

Are these bulbs polarity sensitive?

No. They use a non-polarity design, so they can operate regardless of the positive and negative electrical orientation within a compatible socket.

Do these bulbs have a cooling fan?

Yes. Each bulb contains an integrated high-speed turbine fan that helps draw heat away from the LED chips and supports stable performance during prolonged use.

Do I need to modify the wiring?

No. These bulbs are designed as a direct Plug & Play replacement for a compatible P21/5W BAY15D socket. No rewiring or coding is normally required.

How many bulbs are supplied?

This product is supplied as a pack of two amber LED bulbs.

Are these amber LED bulbs road legal?

Road-use legality depends on the vehicle, lamp unit and intended function. LED retrofit bulbs may not be approved for every exterior lighting application, so please check the relevant vehicle-lighting regulations before installation.
