Plymouth Acclaim high beam and low beam headlight bulbs both use 9004 size bulbs. The replacement chart covers vehicle production spanning 1989 to 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Acclaim uses the 9004 bulb for both high beam and low beam headlights across all model years from 1989-1995.
The 9004 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9004 operates at 12 volts and carries a wattage rating of 65W on the high beam filament and 45W on the low beam filament.
The 9004 uses a P29t base, which is a specific bayonet-style connector that determines physical fitment into the headlight socket.
The 9004 conforms to ANSI standards and is specified for use in the United States and Canada, reflecting a North American market designation.
Because the same bulb type serves both beam functions in the Plymouth Acclaim (1989-1995), a single replacement bulb type addresses both headlight positions on the vehicle.
The P29t base of the 9004 is not interchangeable with other common halogen base types such as H4 or 9007, despite those bulbs also using a dual-filament design, due to differences in base configuration and filament positioning.
