Dual Function (Dome and Reverse) Wiring Harness - Silverado & Sierra (2003-2007 Classic)

$ 19.95

This will get the side lights on your Silverado or Sierra tow mirror to work as both a dome light and a reverse lamp. This is ideal because the light can work as approach lighting when unlocking the truck, but also as a reverse lamp.

The video below will go over how to wire it in.
