Product Details
✓CANBUS ERROR FREE: Super compatible for standard sockets rather than CK sockets. No hyper flash, no warning. With built-in CANBUS system, the 3157 dual color bulbs can alleviate decoding problems. Note: NOT fit TOYOTA TUNDRA and TOYOTA TACOMA. For super few sensitive models such as Silverado, RAM 1500/2500/3500 and Ford F150/F250/F350, extra resistors are needed or get from us
✓600% EXTREMELY BRIGHT: Sequencing 36Pcs Upgraded high brightness 3030SMD chips precisely around each 3157 led bulb, 28W per bulb, High Power and 600% brighter, providing 6500K White light or 3500K Amber Yellow light.

✓DUAL COLOR FUNCTION: This 3157 switchback led bulb with resistor lights up cool white for parking lights or daytime running lights (DRL) but amber yellow for turn signal lights.

The latest cooling system - 12,000RPM silent fan plus Copper cooling ring plus 16Pcs heat sinks plus 6063 aviation aluminum lamp body directly doubles heat dissipation, ensuring longer lifespan up to 60,000 hours
