I picked up one of those relay load resistors from autozone for about 8 bucks I think, they did the job for my led tail lights when they were hyperflashing

Do the GMT900's use a flasher relay or is it built into the BCM or something? If it's on a relay like GMT800's then there's a nice LED-compatible flasher out there that is a far cleaner install than load resistors, and then you don't have to worry about hooking them up or if they're near something they're going to burn or melt (they get goddam HOT.)



About $40 through Amazon but worth it. Have one on my '06 ISS.

You can also hack the factory flasher of that style very easily, just cut one certain leg of the timer IC in there and no more hyperflash. Proved it with my original flasher after getting the aftermarket. Can provide more details if interested...
