What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Not sure if I have clearance there either, I just tied it up on that mounting point for the headlight harness, there's nothing there between the fender liner and the core support so they're just hanging in free air essentially.
I know they get hot as hell.

yep so hot they will melt any plastic that touches them

Driver side motor mount. 2.5 hours on 4wd. Only time I wished I had a 2wd model

Is that fluid from the mount?

Why do they get so hot if they are only used for turn signals. Its not like the turn signals are on continuously like the running lights. Just thinking out loud.

I don't know but they get hot and they get hot pretty quickly

Thats interesting and one if the reasons I am sticking with incandescent bulbs or will have the hyper-flash disabled.

typically the resistor it's self is ceramic and the metal part around it is just a heatsink, attaching it to other metal allows it to dissipate the heat better.
inside the ceramic is a metal strip like a fuse but the ceramic allows the heat to escape and not burn the metal strip creating resistance. at least that's my theory based on taking things apart to see how they work, lol

Sounds right. I understand how resistors make heat. I was just surprised they would make a lot of heat in a flasher circuit. I guess it's 50% duty so sitting at a light for a few minutes would add up.
