LED Switchback Bulb; White/Amber; 3157 - Silverado 1500 Bulb Lights

Enhanced Daytime Running and Signaling. These switchback LEDs deliver bright white for daytime running light functions and instantly transition to amber when the turn signal is activated. They increase visibility to oncoming traffic during daytime conditions and provide a crisp, modern signaling effect in the rear lamp assembly, improving safety during lane changes and turns.

Thermally Optimized, Reliable Design. The aluminum heat sink and integrated driver PCB maintain stable operating temperatures, preventing early failure under continuous DRL operation. High-quality LED chips and optics produce uniform color and beam spread, while built-in resistors ensure proper flash rate without additional wiring modifications.

Installation. Remove the factory bulb, insert the 3157 switchback LED into the socket, rotate to lock, and test DRL and turn signal functions; no extra harness is required.

Application. The LED Switchback Bulb; White/Amber; 3157 fits 2014–2018 Silverado 1500 tail and turn circuits.
