i just installed LED lights on my gmc and i want to know if there is a write up on changing the wiring so i can have my fogs on with the high beams on? the reason i want to do this is because when i hit the highs, it takes a few seconds for the LED's to reach full brightness. thx guys...

 

the thread is in show and shine 4 hi mod

 

ok thanks

 

i looked for this and couldnt find it. i only found the thread that was for keeping the lows on when the highs are on. i want the fogs on when the lows and highs are on. any1?

 

1. i'm guessing you installed HIDs, right? LEDs don't have to warm up.
2. your truck's an 04, right? keep reading through the 4-high thread & you'll get to where they jump a diode from the highs to the fogs.
