Hummer H2 headlight bulbs utilize a 9007 bulb size for both high beam and low beam functions. The replacement chart covers vehicle production spanning 2003 to 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hummer H2 uses the 9007 bulb for both high beam and low beam headlights across all model years from 2003-2009.
The 9007 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9007 operates on a 12-volt electrical system and draws 65 watts on the high beam filament and 55 watts on the low beam filament.
The 9007 uses a PX29t base, which is a specific connector type that determines physical fitment into the headlight socket. A bulb with a different base type is not compatible, regardless of voltage or wattage ratings.
The 9007 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of performance and construction standards shared across those markets.
Because the Hummer H2 uses the same 9007 bulb for both beam functions, the high beam and low beam positions accept the same replacement part, though the filament activated depends on the vehicle's headlight switch position.
