The Dodge B2500 high beam and low beam headlight bulbs both utilize a 9004 bulb size. The replacement chart covers vehicle production spanning 1995 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments to produce both high and low beam output from one housing.
The Dodge B2500 (1995-1998) uses the 9004 bulb for both the high beam and low beam headlight positions.
Because both beam functions are served by the same 9004 bulb, the high and low beam positions are not independent single-filament sockets but share one dual-filament unit per headlight assembly.
The 9004 operates on a 12-volt system and draws 65 watts on the high beam filament and 45 watts on the low beam filament, reflecting the greater luminous output required for high beam use.
The 9004 uses a P29t base, a three-pronged connector that is specific to this bulb family and is not interchangeable with other common base types such as H4 or 9007, despite those bulbs also being dual-filament halogens.
The 9004 and 9007 bulbs share a similar physical form but have reversed high and low beam filament positions within the base, making them incompatible substitutes even though the connector may physically fit in some housings.
The 9004 conforms to ANSI standards recognized in both the United States and Canada, indicating the bulb meets regulated photometric and dimensional requirements for road use in those markets.
