The Dodge B1500 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 bulb is the sole headlight bulb type listed across all model years in these specifications for the Dodge B1500, covering the 1995-1998 range.
The 9004 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to produce both high and low beam output from one unit.
Because the 9004 serves both the high beam and low beam positions on the B1500, the same bulb part number applies to both sockets.
The 9004 operates on a 12-volt electrical system and carries wattage ratings 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. Bulbs with a different base type are not physically compatible with this socket, regardless of voltage or wattage similarity.
The 9004 conforms to ANSI standards recognized in both the United States and Canada, indicating the bulb meets a defined photometric and dimensional standard within those markets.
The 9004 and 9007 are sometimes confused due to their similar dual-filament design, but they are not interchangeable. The 9007 reverses the polarity of the high and low beam filaments relative to the 9004, which can cause incorrect beam operation if substituted.
