Light bar under grill.

[Bernard]

I wanted to put this out there because as far as I know, I was the first to do it on the gmt400 trucks. I’ve seen it on new ones though. I was able to just fit a 12 in light bar behind my grill. The depth was tight but we made it work. I imagine if you had a curved one you could fit something like a 24 but don’t quote me. We welded brackets onto the support and it all managed to fit.

Looks good, but pretty sure your not the first.

X2, people have been doing this to these trucks for nearly a decade now. A couple 2015ish threads for reference:

I would like to do that. Getting really blind at night on my country road with the OEMs.

I hadn’t seen that post but I can’t believe he made that fit. I feel like he might have removed the front brace or something. His looks much better though.

That 30in on the gmc front end looks amazing, squares it off a litter better too.

How did you guys wire up your led bar, I always wanted to do this mod, and can you hook up the lights to the factory diesel fog lights? Or do you have to run a separate harness? I'm thinking about a diesel bumper conversion with fogs and led bars might even do the chin spoiler fogs too and be a Christmas tree driving down the highway.

I have a curved 30 as well I did a few years ago. You have to be careful picking a light bar, one that is very slim and shave the cooling fins off the back where it would interfere with other things.

I built a wiring harness that takes uses the stock light bulb plugs as signal and pulls power from the batteries via relays. That way I get more power to my lights and was able to split off from my highs so that the light bar comes on with the high beams.

Best part is I never cut a stock wire and you could just unplug the harness and plug the stock wires right back in.

I have mine on a separate harness with a switch under my dash, same for KC lights. The only reason I would be carful with it being on with high beams is for police. Personally my light bar is much brighter than high beams and I feel like I could blind people to my sides.
