Plymouth Grand Voyager high beam and low beam headlight bulbs utilize 9007, 9004, or H6054 bulb sizes depending on the specific model configuration. The replacement chart covers vehicle production years spanning 1987 to 2000 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 Plymouth Grand Voyager uses two distinct dual-filament halogen bulb types across its model years: the 9004 and the 9007. Both operate on a 12V system and share the same general halogen capsule construction, though they differ in wattage output and base type, making them non-interchangeable with each other.
The 9004 bulb carries a P29t base and runs at 65W on the high beam filament and 45W on the low beam filament. It serves both the high beam and low beam functions in a single unit, which is the defining characteristic of a dual-filament design.
The 9007 bulb uses a PX29t base and operates at 65W for high beam and 55W for low beam. The higher low beam wattage relative to the 9004 reflects a different filament configuration, and the distinct base type physically prevents cross-installation between the two bulb families.
The Plymouth Grand Voyager (1996-2000) takes the 9007 for both high and low beam positions, while the 1990-1995 model years use the 9004 in both positions.
The 1987-1989 model years offered two headlamp system configurations: halogen capsule headlamps using the 9004 bulb, and sealed beam headlamps requiring a complete lens-and-filament unit replacement rather than a bulb swap.
For the 1988-1989 sealed beam configuration, the H6054 applies to both high and low beam positions. This is a 5x7-inch rectangular sealed beam unit operating at 12V, where the entire assembly is the replaceable component.
The 1987 sealed beam configuration differs between positions: the high beam uses the H4651, while the low beam uses the H4652. Both are 4x6-inch rectangular sealed beam units operating at 12V, with the H4652 being a variant of the H4651.
Because the halogen capsule and sealed beam systems present on 1987-1989 Grand Voyager models require entirely different replacement procedures and parts, confirming the headlamp system type before sourcing a replacement is necessary for correct fitment.
