The Dodge Ram 2500 Van uses a 9004 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 1999 to 2003 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 Dodge Ram 2500 Van uses the 9004 bulb for both high beam and low beam headlights across the 1999-2003 model years.
The 9004 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments that serve both the high beam and low beam functions within one housing.
Because the 9004 handles both beam functions in the Dodge Ram 2500 Van, the high beam and low beam positions share the same bulb specification rather than requiring separate bulb types for each function.
The 9004 operates on a 12-volt electrical system and draws 65 watts on the high beam filament and 45 watts on the low beam filament.
The 9004 uses a P29t base, which is a specific connector type that physically determines which bulbs are compatible with a given socket and prevents substitution with electrically similar but mechanically incompatible bulbs.
The 9004 carries ANSI standardization recognized in both the United States and Canada, meaning its electrical and physical characteristics conform to a defined industry specification rather than a proprietary design.
The 9004 and the visually similar 9007 bulb are not interchangeable despite sharing a dual-filament halogen design, as the 9007 reverses the high and low beam filament positions relative to the base, which would produce incorrect beam alignment if installed in a socket designed for the 9004.
