    looking for a "how to" on getting my fog lights, and possibly my driving lights, to stay on when i turn on my high beams. anybody seen anything like this floating around here ? i searched for something like this but came up empty handed. im running 55 watt HIDs in my driving lits, same in my high beams and 35watt HID's in my fogs (55's melted the fog lights last time). any help would be great

    I've always used the diode method... It's actually very safe if you do it correctly... Essentially all you're doing is jumping the "activation" lead on the relays... It's not sending a lot of power to it, just enough to activate the relay. I have this done to my Av... When my High Beams are activated, my Low Beams and Fog Lights stay on with my High Beams. I also have a mod that keeds my DRL's on all the time. I've been running this set-up in my Av ever since I got it with absolutely NO problems...

    It depends on what model year truck you have also, the older ones can't be done as easily.

    Here's the link to the PDF file that a member of the Avalanche Forum made. Headlight Mod Alot of guys have been running this mod for years with no problems. And some of them are doing it with HIDs...

    THe link I provided is a PDF file that explains it for an Av... Although it won't be exactly the same, it will give you the idea... It's just runing a diode between the activation or trigger post of the relay...
