The Dodge Ram 1500 Van side marker requires a 168 bulb size for proper installation and function. Data for the specific component covers the period from 2001 through 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Ram 1500 Van front side marker position uses two different bulb sizes across the 1999-2003 model years: the 3457 and the 3157.
The 3457 is the front side marker bulb for the 1999-2001 and 2003 model years, while the 3157 applies exclusively to the 2002 model year.
Both the 3457 and 3157 are ANSI-standardized dual-filament wedge bulbs of the T25 type, rated at 12V with a 27W/7W output, meaning one filament draws 27 watts and the other draws 7 watts.
Despite sharing identical electrical ratings and the same T25 wedge form factor, the 3457 and 3157 are distinct part numbers and are not confirmed as interchangeable for the Dodge Ram 1500 Van without verifying socket compatibility for the specific model year.
The rear side marker position on the Dodge Ram 1500 Van uses the 168 bulb for the 1999-2001 model years.
The 168 is an ANSI-standard single-filament miniature wedge bulb of the T10 type, rated at 12V and 4.9W, which is considerably lower in wattage than the dual-filament T25 bulbs used at the front.
The T10 and T25 designations refer to the physical size of the wedge base, with T10 being the smaller of the two, making the front and rear side marker bulbs physically incompatible with each other's sockets.
All three bulb types listed, the 3457, 3157, and 168, conform to ANSI standards applicable in both the United States and Canada.
