Powerful 1800LM White LED Output

These premium P21W LED bulbs produce up to 1800 lumens of bright white light from each bulb, providing a significant improvement over many conventional filament bulbs.

The crisp 5700K Cool White colour delivers a clean, modern appearance while improving visibility in compatible reverse light, daytime running light and rear lighting applications.

Single-Intensity P21W Operation

The P21W (382) is a single-intensity bulb type designed to perform one lighting function. Unlike a dual-intensity P21/5W bulb, it operates at one brightness level whenever the relevant lighting circuit is activated.

This makes it suitable for a wide range of applications, including reverse lights, daytime running lights, rear fog lights and selected brake or indicator applications, depending on the vehicle and required bulb colour.

Why Upgrade to LED?

Compared with conventional filament bulbs, LED technology provides faster illumination, a cleaner light output and reduced power consumption.

The instant response of the LED chips allows the bulb to reach full brightness immediately, while the efficient aluminium construction and active cooling system help support stable long-term performance.

Intelligent Super Canbus Technology

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

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

Advanced Active Cooling

A built-in high-speed turbine cooling fan continuously draws heat away from the LED chips, helping maintain stable brightness during prolonged use.

The fan works together with the CNC-machined aviation-grade aluminium housing to provide efficient heat dissipation and support a long operating life.

360° LED Light Distribution

The multi-sided LED chip arrangement produces wide and even illumination throughout the lamp reflector.

This design helps closely replicate the light position of the original filament bulb, supporting consistent light distribution and improved visibility from different viewing angles.

Ideal Applications

• Reverse Lights
• Reversing Lamps
• Daytime Running Lights
• Rear Fog Lights
• Brake Lights, vehicle dependent
• Indicator Lights, only where white output is appropriate
• Rear Position or Auxiliary Lights, vehicle dependent
• Any compatible application requiring a P21W bulb
• Any compatible application requiring a 382 bulb
• Any compatible application requiring a BA15S base

Technical Specifications

P21W and 382 Bulb Compatibility

P21W and 382 are commonly used references for the same single-filament automotive bulb type. These bulbs use a BA15S single-contact base with two side locating pins positioned directly opposite each other at the same height.

Do not confuse the BA15S base with similar-looking bulb types such as BAY15D, BA15D, BAZ15D or BAU15S. These bases use different contact or locating-pin arrangements and are not interchangeable.

Please remove and inspect your existing bulb before ordering, paying particular attention to the side-pin position and the number of electrical contacts on the bottom of the bulb.

Frequently Asked Questions

Will these P21W LED bulbs fit my vehicle?

These bulbs are designed for vehicles that use a P21W (382) bulb with a BA15S single-contact base. Please remove and inspect your existing bulb, consult your vehicle handbook or compare the base before ordering.

Are P21W and 382 the same bulb type?

Yes. P21W and 382 are commonly used references for the same single-intensity automotive bulb type. They normally use a BA15S base with one bottom contact and two side pins positioned opposite each other at the same height.

What is the difference between P21W and P21/5W?

P21W is a single-intensity bulb with one electrical contact and one light output. P21/5W is a dual-intensity bulb with two electrical contacts and separate high and low outputs. The bulb bases are different and are not interchangeable.

What colour light do these bulbs produce?

These bulbs produce a crisp 5700K Cool White light. Please ensure that white light is suitable and permitted for the intended lamp position before installation.

Can these bulbs be used as reversing lights?

Yes, provided your vehicle uses a P21W (382) BA15S bulb in the reversing lamp. Their bright 5700K white output makes them particularly suitable for compatible reverse light applications.

Can these bulbs be used as daytime running lights?

They may be suitable for vehicles using a P21W BA15S bulb for the daytime running light function. Please confirm the original bulb type, available space and lamp configuration before ordering.

Are these bulbs Canbus compatible?

Yes. They contain built-in Super Canbus electronics designed to reduce dashboard bulb warnings, flickering and shut-off issues on many modern vehicles. Some highly sensitive vehicles may still require an additional resistor or decoder.

What is the difference between BA15S and BAU15S?

A BA15S base has two side pins positioned opposite each other at the same height. A BAU15S base has offset locating pins and is commonly used for PY21W indicator bulbs. The two bases are not interchangeable.

Are these bulbs polarity sensitive?

No. They use a non-polarity design, allowing them to operate regardless of the positive and negative electrical orientation within a compatible socket.

Do these bulbs have a cooling fan?

Yes. Each bulb includes a built-in high-speed turbine fan that helps remove heat from the LED chips and maintain stable performance during prolonged operation.

Do I need to modify the wiring?

No. These bulbs are designed as a direct Plug & Play replacement for a compatible P21W BA15S socket. No rewiring or coding is normally required.

How many bulbs are supplied?

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

Are these white 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.
