## Description

B21 Series 3157 Switchback LED Bulbs Built in Resistor CANBUS Error Free Anti Hyper Flash T25 3057 3457 4157 Bulbs White and Amber 600% Super Bright Turn Signal Light DRL Parking Light

## Features

- CANBUS ERROR FREE Super compatible for 99% Vehicles. No hyper flash, no errors, no warning. With built-in 2023 CANBUS system, these 3157 dual color bulbs can directly alleviate decoding problems without trouble to prepare external resistors. Auxbeam offers 1-year warranty. Note: NOT fit TOYOTA TUNDRA 2014-2021 and TOYOTA TACOMA 2016-2020. For super few sensitive models such as Chevrolet silverado and 2014-2018 Dodge RAM 1500, 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.
- 360 FULL CLEAR BEAM Each 3157 led bulb provides 360 full illumination without dark spot or shadow. Compatible for both US standard sockets and CK sockets. Fit socket 3157, 3157A, 3157NA, 3157R, 3047, 3057, 3357, 3457, 4057, 4114, 4157, T25, etc. No polarity, no drilling, no wiring, no damage, just Plug and Play.
