Lucas Lighting 3157 LED BULB SWITCHBACK 3157 AMBER/WHITE

PN. M-3157SB

M-3157 LED High Output CANBUS Bulb Pair (2 Bulbs) Available Colors Switchback or White

The 3157 style is a dual output that can be used as a reverse bulb or turn signal/marker light.  It is designed to have a lower output from the typically constantly used mode (ex: a marker for the corner of your vehicle) and a high output mode when the second output is engaged (turn signal).  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. 

The 3157 M Series bulbs redefine both performance and compatibility standards in the automotive aftermarket.  Like our headlight bulbs, we recognize optimizing the light source position is key to having a proper pattern from the housing.  You will notice that we now use fewer but much higher power LED chipsets oriented as closely as possible to the original bulb filaments.  We have also incorporated the newest CANBUS technology to achieve compatibility with greater than 99% of vehicles without causing a bulb out error.  In turn signal applications, these new bulbs eliminate the need to add resistors to the circuit to solve fast blinking issues.
