Chevrolet Tracker high and low beam headlight bulbs utilize 9003 and 9004 size specifications. The replacement chart covers vehicle production spanning 1998 to 2004.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is a dual-filament halogen type operating at 12V with a 60W high beam filament and a 55W low beam filament, fitted with a P43t base. Its dual-filament design allows a single bulb to serve both high and low beam functions within one housing.
The 9004 bulb is also a dual-filament halogen type operating at 12V, but with a 65W high beam filament and a 45W low beam filament, and it uses a P29t base rather than the P43t base found on the 9003.
The P43t and P29t base designations indicate physically different connector configurations, meaning the 9003 and 9004 bulbs are not interchangeable despite both being dual-filament halogen types rated at 12V.
The Chevrolet Tracker uses the 9003 bulb for both high beam and low beam headlights across the 1999-2004 model years.
The 1998 Chevrolet Tracker uses the 9004 bulb for both high beam and low beam headlights, which differs from the 9003 specification used in subsequent model years.
Both the 9003 and 9004 are ANSI-standard bulbs recognized in the United States and Canada, placing them within a standardized North American bulb classification system.
