About this item

• CANBUS ERROR FREE: Super compatible for 99% Vehicles. No hyper flash, no errors, no warning. With built-in 2023 CANBUS system, these 3157 amber bulbs can directly alleviate decoding problems without trouble to prepare external resistors. Note: Auxbeam offers 1-year warranty. For some super few sensitive models or if you replace the rear turn signal for Pickup/Truck/Lorry, extra resistors may be needed or message us to get.
• NOT FIT CK SOCKETS: Each 3157 led bulb provides 360° full illumination without dark spot or shadow. Only compatible for US standard sockets. Fit socket 3056, 3156, 3157, 3157A, 3157NA, 3157NAK, 3157K, 3047, 3057, 3357, 3457, 4057, 4157, 3757, 4157NA, T25, etc. No polarity, no drilling, no wiring, no damage, just Plug and Play. If any questions or flashing issues, please message us for free solutions.
• DUAL BRIGHTNESS: This 3157 amber led bulb with resistor supports dim mode for only parking light or daytime running light (DRL) and bright mode for only turn signal light. When used as turn signal bulbs, the 3157 led bulb with built in resistor flash "amber-off-amber-off",making it easier to see from a distance.
• 600% EXTREMELY BRIGHT: Sequencing 36PCs Upgraded high brightness 3030 SMD chips precisely around each 3157 led bulb, 28W per bulb, High Power and 600% brighter, providing 3500K Amber Yellow light for turn signals. Stronger light penetration output for 40% more visibility than ordinary leds. Instant-on response without warm-up time, 360° illumination without dark spot, brighter and safer when turning.
• 4-LAYER COOLING DESIGN: Water and dust resistant with IP68 rating. Equipped with a stable current IC driver to prevent interference with digital or VHF radio signals. Incorporates a cooling system with a 12,000RPM silent fan, Copper cooling ring, 16 heat sinks, and 6063 aviation aluminum lamp body for enhanced heat dissipation and extended lifespan of up to 60,000 hours.
