Dorman Headlight Assembly P/N:1590533
Dorman 1590132 left headlight assembly for the 1999-2004 Oldsmobile Alero lights the road ahead on the left side of the car.
A cracked or clouded lens, or moisture inside the housing, can mean a headlight assembly needs replacing. These signs alone do not prove the assembly is the problem, since a burned-out bulb can look similar. This listing is one left headlight assembly; the car takes one on each side, and the right side is ordered separately.
It fits the 1999-2004 Oldsmobile Alero. This Dorman replacement was reverse-engineered to match the stock headlight and built to the exact original dimensions for a proper fit.
