Chevrolet SSR high beam headlight bulbs use 9005XS size while low beam headlight bulbs use H11 size. The replacement chart covers 2003 through 2006 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet SSR uses the 9005XS for high beam headlights across all model years from 2003-2006.
The 9005XS is an ANSI-standard single-filament halogen bulb operating at 12V and 65W, built on a straight 180-degree base configuration.
The low beam headlight position on the SSR (2003-2006) takes the H11 bulb, a single-filament halogen type rated at 12V and 55W with a PGJ19-2 base.
The H11 is governed by ECE standards, which are used across Europe and internationally, though it also carries approval for use in the United States.
The 9005XS and H11 are not interchangeable with each other. The two bulbs differ in base type, wattage, and governing standard, making each one specific to its designated headlight position.
The "XS" designation in 9005XS indicates a physically shorter bulb body compared to the standard 9005, a distinction relevant to fitment in housings with tighter clearance requirements.
Both bulb types are single-filament designs, meaning each serves only one lighting function rather than combining high and low beam output within a single unit.
The wattage difference between the two positions, 65W for the high beam and 55W for the low beam, reflects a standard halogen headlight configuration where the high beam draws more power to produce greater output.
