Our 2006 has the off road lights mounted on the roof and one is broken and no longer works. The other looks like a replacement from a 90s C1500 if my son't sleuthing skills are accurate.

The housing looks good with no cracks. Has anyone replaced the individual lights with aftermarket leds?

 

 

Buy this. Remove the lamp assemblies from the grille and replace the ones on your roof (same lamps as your roof lamps), then replace the halogen bulbs with the LED equivalents. Or, buy (2) and add a set to your grille. I bought a set for my H3 and they added a significant amount of light over the hi-beams.

That's one idea!

I meant sealed led lights of a similar size, not just bulbs.

 

We are thinking about buying 2 sets. They are expensive to just grab the lights out of but they would at least match.
