Dodge B350 front and rear side marker bulbs utilize 194 and 168 bulb sizes depending on position and model variation. The replacement chart covers 1981 to 1994 production years 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 B350 front side marker position uses two distinct bulb sizes across its model years, with the 194 bulb fitted in 1981-1991 and 1994, and the 168 bulb fitted in 1992-1993.
The rear side marker position on the B350 also alternates between the two sizes, with the 194 bulb used in 1992-1993 and the 168 bulb used in 1994.
Both the 194 and 168 bulbs are ANSI-standardized miniature wedge types classified under the T10 form factor, meaning they share the same physical wedge base style.
Despite sharing the same T10 wedge base, the 194 and 168 bulbs are not identical in power draw. The 194 operates at 3.78W while the 168 operates at 4.9W, both on a 12V circuit.
Because the 194 and 168 share the same T10 wedge base, one may physically fit into a socket intended for the other. However, the difference in wattage means the two are not confirmed interchangeable replacements for the B350 without referencing the year-specific fitment data.
The front side marker position on the Dodge B350 used the 194 bulb across the majority of its listed model years, spanning 1981-1991 and returning again in 1994, with only 1992-1993 specified as 168.
In 1994, the front and rear side marker positions on the B350 use opposite bulb sizes from each other, with the front requiring a 194 and the rear requiring a 168.
In 1992-1993, the front and rear side marker positions again use opposite bulb sizes, but in reverse configuration relative to 1994, with the front specified as 168 and the rear as 194.
