Chevrolet Venture high beam and low beam headlight bulbs both utilize a 9004 bulb size. The replacement chart covers vehicle production spanning 1997 to 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 bulb is the sole headlight bulb type specified for the Chevrolet Venture across all listed model years, 1997-2005.
The 9004 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments within one housing, one for high beam output and one for low beam output.
Because the 9004 serves both filament functions within a single bulb, the high beam and low beam positions on the Venture share the same bulb type rather than requiring separate part numbers for each function.
The 9004 operates on a 12-volt electrical system and carries wattage ratings of 65W on the high beam filament and 45W on the low beam filament.
The 9004 uses a P29t base, which is a specific connector and socket configuration. Bulbs with different base types are not physically interchangeable with this socket, regardless of similar wattage or voltage ratings.
The 9004 is an ANSI-standardized bulb type recognized in both the United States and Canada, meaning production of this bulb conforms to defined performance and construction standards across those markets.
The 9004 is sometimes confused with the 9007 bulb, which shares a similar dual-filament halogen design but uses a different base configuration and reversed polarity wiring. The two types are not interchangeable.
