# Fleece Performance 04.5-07 GM Duramax 6.6L LLY / LBZ GM All Lights On Brighten up your driving experience with this simple upgrade inside your fuse box. Simply install the GM All Lights On Module to allow your high-beams, low-beams and fog lamps to simultaneously illuminate the road ahead. Once installed the GM All Lights On Module will turn on the high-beams, low beams and fog lamps when you turn on your high-beams. When the high-beams are NOT turned on your low-beams and fog lights will function normally. Add the supplied spade terminal to provide a signal ground when the high-beams are turned on. This will allow you to control an accessory relay with the high-beam switch. WARNING: The spade terminal signal ground is NOT intended to provide a high amperage ground. It is only rated for a signal ground that will control a relay. Fitment Guide: 2003-2007 Classic 2500-3500 Silverado/Sierra Installation: 1.
