Highlights
- 6000K White Output: SEALIGHT SLJ4 1156/BAU15S/PY21W LED backup/reverse, brake, tail light, and DRL bulbs deliver 3,000LM and 30W per pair. White light helps illuminate the area behind your vehicle.
- 360° Chip Lighting: Each bulb has 36 3030 SMD chips for full-angle illumination, helping reveal obstacles when reversing.
- Multi-Position Use: Use these bulbs for backup/reverse, brake, tail, or DRL positions when the socket matches. For turn signals, pair them with a yellow lens for amber output.
- Plug-and-Play Design: The non-polarity design and OEM-size base simplify replacement in matching sockets. The bulbs support standard and CK/SRCK sockets.
- CANBUS and Durability: The built-in resistor helps address hyperflash, while the aluminum housing supports heat dissipation. IP67 protection and a 50,000-hour rating support long-term use.

Product Description


FAQs
Q1. Is this the same base as a BAU15S or PY21W?
A1. The pins decide it: 1156 sets them at 180 degrees, while BAU15S and PY21W set them at 150, so the old bulb shows which holder the truck has.
Q2. Will the pair fit my holder?
A2. Match the number on the old bulb to the pair first; the driver is non-polarity, so only the pin angle decides whether it seats and locks.
Q3. Will it set a warning?
A3. Usually not: the resistor and IC hold the load steady at 30W per pair. If a message appears, support ships a free decoder for that circuit.
Q4. Is 3,000LM right for a turn signal?
A4. Yes. 1,500LM per bulb is strong for a turn lamp, and behind an amber lens it reads clearly in daylight without washing the colour out.
