I bought a 30 inch curved light bar from Amazon. If you type in hummer h3 light bar it will pop right up. I'm curious as to how you did your install? You removed the whole bumper? Or just the lower grille insert? How did you run your wiring harness into the cab? I have had this light bar since Christmas and am very eager to install it! Thanks for any help.

 

Only good way is to remove the whole bumper.

There are already (4) unused wires going through the firewall, intended for off road lights from the factory. The ends are up under the dash inside and behind the battery under the hood. Do a search; there is alot of info on finding/using them (use only as a switching circuit, not for the full power to the light bar).
