Dorman Headlight Assembly P/N:1570033
Dorman 1591038 right headlight assembly for the 2004-2006 Chevrolet Colorado lights the road ahead from the right side of the vehicle. It was reverse-engineered to match the stock headlight on specific vehicles, so it looks and functions like the headlight it replaces.
A cracked or hazy lens, moisture inside the housing or a dim beam can mean the headlight assembly needs replacing. These signs alone do not prove the assembly is the problem, since a worn bulb can dim the light too.
It is the right-side headlight for the 2004-2006 Chevy Colorado. This listing is one assembly; the right side takes one, and the left side is a separate part ordered separately.
