Had a buddy ask to do an install for him. He wanted two red and two blue LEDs wired to his front and rear. I put a red and blue on the grill, on either side of the GMC logo. The rear two got put below the tailgate, almost below the STT lights. No siren yet. I installed one switch next to the gear lever.

Nice truck, I dunno if it's just the angle, but those TIR3-type lights look bulky and kinda tacky (plus they're not even matching).
For someone that has a sierra Denali, I think they should've invested some more money in a little better warning and a cleaner look (i.e. A pair Cannon LAWs in the rear to replace the reverse or brake lights)
