The Dodge B2500 brake light uses 2458 and 3157 bulb sizes for the rear lighting system. Data for the specific components covers the range from 1995 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge B2500 uses the 3157 bulb for the brake light position across the 1995-1998 model years.
The 3157 is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and a 7W low filament, conforming to ANSI standards for the US and Canada. The dual-filament design allows a single bulb to serve both brake and running light functions.
The Center High Mount Stop Light on the B2500 does not use a consistent bulb size across the 1995-1998 model years, which means direct interchangeability between model years cannot be assumed for that position.
The 1995 and 1997 B2500 share the 912 bulb for the Center High Mount Stop Light.
The 912 is a T15 wedge bulb rated at 12V and 12W, and it is a variant of the 921 bulb. Despite the physical similarity, the lower wattage of the 912 distinguishes it from the 921 and 922.
The 1998 B2500 uses the 921 bulb for the Center High Mount Stop Light, rated at 12V and 16W, which draws more power than the 912 used in the 1995 and 1997 models.
The 1996 B2500 uses the 922 bulb for the Center High Mount Stop Light. The 922 shares the same T15 form factor and 12V, 16W rating as the 921, making them electrically equivalent, though they carry different ANSI designations.
All bulb sizes listed across both positions conform to ANSI standards applicable in the US and Canada.
