- CANBUS ERROR FREE: Super compatible for standard sockets rather than CK sockets. No hyper flash, no warning. With built-in 2023 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 2023 Upgraded high brightness 3030SMD chips precisely around each 3157 led bulb, 28W per bulb, High Power and 600% brighter, providing 6500K Cool White light or 3500K Amber Yellow light. Instant-on response without warm-up time. More noticable when turning, guard your driving safety.
- 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. Unlike most turn signals flashing "amber-white-amber-white" on the market, the Auxbeam 3157 turn signals flash "amber-off-amber-off", making it easier to see from a distance.
- 4-LAYER COOLING SYSTEM: IP68 waterproof and dustproof. The built-in 2023 stable current IC driver avoids digital or VHF radio signal interference. The 2023 latest cooling system - 12,000RPM silent fan + Copper cooling ring + 16Pcs heat sinks + 6063 aviation aluminum lamp body directly doubles heat dissipation, ensuring longer lifespan up to 60,000 hours.
- NOT FIT CK SOCKETS: Only compatible with US standard sockets. Please refer to the CK sockets precautions on the pictures. Designed to be polarity sensitive, and if the bulbs don’t light up, please flip the plug and try again. Fit socket 3157, 3157A, 3157NA, 3057, 3057A, 3457, 3457A, 4057, 4157, 4157NA, T25, etc. No drilling, no wiring, no damage, just Plug and Play.
- 360°FULL CLEAR BEAM: Each 3157 led bulb provides 360° full illumination without dark spot or shadow. If any questions or flashing issues, please message us for free solutions.
