3030 SMD
7 High-Output LEDs Seven 3030 SMD LED chips provide strong, responsive illumination from a compact automotive bulb.
OPTICAL LENS
Forward Light Projection The forward-facing optical lens complements the side-mounted LEDs and helps distribute light from the end of the bulb.
METAL BODY
Passive Heat Management Metal-bodied construction helps transfer heat away from the LED components without requiring a cooling fan.
Modern Vehicle Compatibility
CANBUS Ready & 12V–24V
Integrated electronics are designed to improve compatibility with vehicle bulb-monitoring systems and reduce warning messages commonly associated with low-current LED replacement bulbs.
CANBUS compatibility varies by vehicle. These bulbs are designed to reduce bulb-out warnings, but vehicle monitoring systems differ between manufacturers and models. Some applications may still require an additional resistor, decoder or other corrective component.
Engineered Construction
Designed For Reliable LED Performance
The LED chips, integrated driver electronics, metal housing and forward optical lens are combined with a traditional BA15s single-contact bayonet fitting for compatible P21W applications.
Three LED Light Colours
Choose White, Amber Or Red
Choose the LED colour that matches the original function and required colour of your vehicle's lighting system.
WHITE For compatible white-light P21W applications such as reversing lights or other vehicle functions where a white BA15s bulb is required.
AMBER For compatible indicator and signalling applications using a BA15s fitting where an amber light source is required.
RED For compatible single-function rear-lighting applications requiring a red P21W / BA15s light source.
Vehicle Lighting Applications
Match The Colour To The Lighting Function
P21W bulbs are used in a variety of exterior vehicle lighting positions. Application varies by vehicle, so always check the original bulb reference, required light colour and lamp function before ordering.

BA15s Fitment Guide
Single Contact & Equal-Height Pins
The P21W / 382 fitting uses a BA15s base with one electrical contact underneath and two opposite locating pins positioned at the same height.
Avoid Incorrect Fitment
382 vs 380 vs 581
These bulb types can look similar, but their bases and electrical functions are different. Check the existing bulb carefully before ordering.
✓ 382 / P21W / BA15s Single-intensity bulb with one electrical contact and two opposite locating pins at equal height. This is the fitting covered by this listing.
✕ 380 / P21/5W / BAY15d P21/5W is a dual-intensity bulb with two electrical contacts and a different bayonet-pin arrangement. It is not the same fitting as P21W.
✕ 581 / PY21W / BAU15s PY21W uses an offset locating-pin arrangement. A BAU15s bulb should not automatically be considered interchangeable with BA15s.
Always check before ordering: compare the existing bulb reference, number of electrical contacts, bayonet-pin arrangement and required light colour with this product.
CANBUS Ready – Not Universally Error-Free The integrated electronics are designed to reduce LED bulb-out warnings on compatible vehicles. Vehicle monitoring systems vary, however, and some applications may still require an additional resistor, decoder or other corrective component.
382 is the commonly used UK reference for the P21W single-intensity automotive bulb using a BA15s bayonet fitting.
What type of base does a P21W bulb use?
P21W uses a BA15s base with one electrical contact underneath and two opposite locating pins positioned at the same height.
What is the difference between 382 P21W and 380 P21/5W?
382 / P21W / BA15s is a single-intensity, single-contact bulb. 380 / P21/5W / BAY15d is a dual-intensity, dual-contact bulb and uses a different bayonet base.
Is P21W the same fitting as PY21W?
No. P21W uses a BA15s fitting with opposite locating pins at equal height, whereas PY21W normally uses a BAU15s base with an offset locating-pin arrangement.
Which LED colour should I choose?
Select the colour required by the original lighting function. White is suitable for compatible white-light applications such as reversing lights, Amber for compatible signalling applications and Red for compatible rear red-light applications.
Are these P21W LED bulbs CANBUS error free?
They include CANBUS-ready electronics designed to reduce bulb-out warnings, but compatibility varies between vehicles and some applications may still require additional resistance or decoding.
Are these suitable for 24V vehicles?
The bulbs are designed for compatible 12V–24V DC vehicle electrical systems.
How many bulbs are supplied?
The price is for one pair containing two bulbs in the selected colour.
What warranty is supplied?
HIDS-DIRECT supplies these bulbs with a 1-year warranty.
