LUCAS LIGHTING 1157 LED BULB SWITCHBACK 1157 (AMBER/WHITE)

LUCAS LIGHTING LED BULB SWITCHBACK 1157 (AMBER/WHITE)

M-1157 LED High Output CANBUS Bulb Pair (2 Bulbs) Available Colors Red, Switchback or White The 1157 style is a dual output that can be used as a reverse bulb, turn signal/marker light, or brake light/marker light. It is designed to have a lower output from the typically constantly used mode (ex: tail lights when you are not using your brakes and headlights are on) and a high output mode when the second output is engaged (turn signal, brakes applied). We offer this bulb as a switchback style for use on the front of vehicles where you would like to have the marker light illuminate in white rather than traditional amber. When the turn signal is engaged on a switchback, the color changes to traditional amber.
