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.
2003-2007 Classic 1500, 2500, 3500 Silverado/Sierra and full size GM - or - if your fuse box is laid out like the one shown below
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

This mod can be done with the 2 diodes for about $4 but the fleece all lights on board makes for a cleaner and safer mod that's worry free. This stays in place and won't get crossed connected like the cheaper mod could. I feel it's a smarter idea to spend $15 extra and save hundreds in electrical issues.

I used this clever little device to replace the BriteBox controller i installed ten years earlier. This little board allowed me to completely remove the excess wiring, relay box, and connectors the BriteBox required. SUPER simple to install and so far seems to be rugged enough to cope with the hundreds of rough dirt roads i travel weekly. Must buy if you want that "all on" when you hit the high beams.
