The Dorman 74379 is a replacement dome light housing for GMC Canyon and Chevrolet Colorado pickups. It restores the interior overhead light when the original lens or housing cracks, yellows or stops holding the bulb. It is a direct-fit part aimed at owners doing their own repair, and it is a cheaper alternative to a dealer-only assembly. It is not an upgrade: output and fit match the factory part, and the bulb is typically not included.

Owners who bought it generally report it fits and works as a stock replacement. Some note the plastic feels lighter than the original and that the bulb must be sourced separately.
