The Dodge B1500 side marker requires a 194 bulb size for the lighting component. Data for the specific bulb requirements covers the range from 1995 to 1996.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge B1500 front side marker uses two distinct bulb sizes across its model years: the 194 for 1995-1997 and the 3457 for 1998.
The 3457 is a dual-filament T25 wedge bulb rated at 12V with a 27W/7W output, making it a notably larger and more complex component than the single-filament miniature bulbs used in other positions on the same vehicle.
The 194 is a miniature T10 wedge bulb operating at 12V and 3.78W, conforming to ANSI standards applicable in both the United States and Canada.
The rear side marker position on the Dodge B1500 uses the 168 bulb across all four model years from 1995-1998, indicating no change in rear side marker specification throughout the vehicle's production run in this range.
The 168 is also a miniature T10 wedge bulb at 12V, but draws 4.9W, placing it at a slightly higher wattage than the 194 despite sharing the same T10 form factor.
Because the 194 and 168 share the T10 wedge form factor, physical fitment between the two is possible, but their wattage ratings differ and they are not designated as interchangeable in these specifications.
The 3457 used in the 1998 front side marker position is a T25 wedge bulb, which is physically larger than the T10 form factor and is not interchangeable with the 194 or 168 bulbs used elsewhere on the vehicle.
The dual-filament nature of the 3457 means it contains two separate circuits within a single bulb, a characteristic absent in both the 194 and 168, which are single-filament types.
