Introducing the Switchback

Two Colors - One Bulb

The Switchback Bulb is designed to light bright white when the running lights are on.  When the turn signal is activated, the light will automatically instantly switch from white to amber, and flash.  These are great for clear front turn signals and for meeting import standards on European made autos. 

Note:  Load Equalizers or a special flasher may have to be added to restore a normal blinker rate if switching a turn signal bulb to an led.  We have specially modified flashers, or load equalizers available here: Click here for LED Load Equalizers Led Turn Signal Fix
