If you only have 1.5" of depth behind the grill, the 911EP TDWL series of lights will work well. They are 1.47" deep. The Sound Off UltraLite series of lights are 1.70" deep. Either would work great if you ended up having a little more room, but if you only have the 1.5" of depth and 30ish of width you'll have to go with a TDWL 24 (of you have 36" of width a TDWL 36 will work)NC4AB said:Looking to find out if any one has installed a LED lightbar behind the grille of a 2008 (or newer) GMC Sierra 2500HD.
Looks like I have about 1.5" of depth and 30"+ inches across the grill.
Didn't know if there are any thin bars available.
