The Hummer H3 high beam and low beam headlight assemblies both utilize a 9008 bulb size. The replacement chart covers vehicle production spanning 2006 to 2010.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9008 bulb is the sole headlight bulb type specified for the Hummer H3 across all listed model years, covering both high beam and low beam functions for 2006-2010.
The 9008 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 65W for high beam operation and one rated at 55W for low beam operation.
Because the 9008 serves both beam functions within one unit, the Hummer H3 headlight assembly uses a single bulb per side rather than separate bulbs for each beam mode.
The 9008 operates on a 12V electrical system, which is standard for passenger vehicle applications.
The bulb uses a P26t base, a specific pin-style connector that determines physical fitment into the headlight housing socket.
The 9008 designation follows ANSI standards recognized in both the United States and Canada, classifying it as a regulated specification rather than a proprietary part number.
The 9008 is also commonly cross-referenced as H13 in international markets; however, fitment compatibility between these designations depends on the specific socket and housing design of the vehicle.
