The Fleece FPE-GM-ALO-37 GM All Lights On Module for your 03-07 GM 2500HD/3500HD will 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 - or - if your fuse box is laid out like the one in the gallery above.

1. Remove the relays labeled: FOG LP, HDLP-LOW, DRL, HDLP-HI
2. Lay the GM All Lights On circuit board in the location shown below
3. Reinstall the four relays back into their original location

The FLEECE FPE-GM-ALO-37 GM ALL LIGHTS ON MODULE will only work on the 2003-2007 GM 2500/3500 applications. This is due to slight differences between the 2001/2002 2500/3500 and 2003-2007 GM 2500/3500 electrical systems.

Will this module work on the 2013 Silverado 1500?
