Fleece 03-07 6.6L Duramax "All Lights On" Module | FPE-GM-ALO-37 | 2003-2007 Chevy/GMC Duramax 6.6L

Wish you could keep your headlights, high beams, and fog lights all on at the same time on your 2003-07 full size GM truck? Fleece Performance All-Lights-On modules will allow you to do just that. These modules allow a simple upgrade that you can perform inside of your fuse box. Simply install one of these GM All-Lights-On modules to allow your high-beams, low-beams, and fog lamps to simultaneously illuminate the road ahead. Once the modules are installed, they will turn on high-beams, low beams, and fog lamps when your high-beams are turned on. When the high-beams are turned off, the low-beams and the fog lights will function normally. Add the supplied spade terminal to provide a signal ground when the high-beams are turned on to allow you to control an accessory relay with the high-beam switch. Brighten your driving experience with Fleece Performance All-Lights-On!
