Dorman Headlight Assembly P/N:1590533
Dorman 1592134 left headlight assembly for the 2003-2007 Cadillac CTS holds the lens, housing and bulbs that light the road ahead. Dorman reverse-engineered it from the stock headlight and built it to the original's exact dimensions for proper fit.
A cracked or hazy lens, moisture inside the housing or a lamp that stays dark can mean the assembly is due for replacement. These signs alone do not prove the assembly is the problem, since a blown fuse can leave a lamp dark too.
It fits the 2003-2007 Cadillac CTS. This listing is one left assembly, and the car takes one on that side; the right side is a separate part ordered separately.
