Auxbeam 2023 B21 Series 1157 LED Bulbs Amber Yellow Built in Resistor CANBUS Error Free Anti Hyper Flash 1157A 1157NA 2057 2357 2357A 2357NA 7528 1034 Blinker Bulb 600% Super Bright Turn Signal Light - B21-1157-A

• CANBUS ERROR FREE: Super compatible for 99% Vehicles. No hyper flash, no errors, no warning. With built-in 2023 CANBUS system, these 1157 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. 600% EXTREMELY BRIGHT: Sequencing 36PCs Upgraded high brightness 3030 SMD chips precisely around each 1157 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. DUAL BRIGHTNESS: This 1157 amber led bulb with resistor supports dim light mode for only parking light or daytime running light (DRL) and bright light mode for only turn signal light. When used as turn signal bulbs, the 1157 led bulb with built in resistor flashes "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 of 1157 turn signal bulb 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. 360°FULL CLEAR BEAM: Each 2057 led bulb provides 360° full illumination without dark spot or shadow. Compatible for both US standard sockets and CK sockets.
