Dodge B250 front and rear side marker bulbs utilize 194 and 168 bulb sizes depending on position and model year. 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 B250 front side marker uses two distinct bulb sizes across its model years: the 194 for most years and the 168 for 1992-1993.
Both the 194 and 168 bulbs are ANSI-standardized miniature wedge types classified under the T10 form factor, operating at 12 volts.
The primary difference between the two bulbs lies in wattage. The 194 draws 3.78W, while the 168 draws 4.9W, making them electrically distinct despite sharing the same T10 wedge base.
Because the 194 and 168 share the T10 wedge base, they are physically interchangeable in the socket, but their wattage difference means substituting one for the other alters the intended power draw of the circuit.
The Dodge B250 front side marker relied on the 194 bulb from 1981-1991 and again in 1994, representing the dominant fitment across the vehicle's production span covered by these specifications.
The 1993 model year is notable for a reversal in bulb assignment relative to adjacent years: the front side marker uses the 168 while the rear side marker uses the 194, the opposite of the 1994 configuration.
For the 1994 model year, the front and rear side markers use different bulbs. The front position takes the 194 and the rear takes the 168.
The rear side marker data covers only 1992-1994, with the 194 specified for 1992-1993 and the 168 specified for 1994.
