Dodge B150 front and rear side marker bulbs utilize 194 and 168 bulb sizes across different positions on the vehicle. 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 B150 front side marker uses two bulb sizes across its model years: the 194 and the 168, both of which are ANSI-standard miniature wedge bulbs rated at 12 volts.
Both the 194 and 168 bulbs share the same T10 wedge base form factor, meaning they are physically interchangeable in terms of socket fitment.
Although the 194 and 168 bulbs fit the same T10 socket, they differ in wattage. The 194 draws 3.78W, while the 168 draws 4.9W, making them electrically distinct.
The 194 bulb is the dominant front side marker specification for the Dodge B150, covering model years 1981-1992 with the exception of 1992 and 1993, as well as 1994.
The 1992-1993 front side marker position on the B150 specifies the 168 bulb rather than the 194, representing a departure from the surrounding model years.
The rear side marker position on the Dodge B150 also alternates between the 194 and 168 bulbs, with 1993-1994 split between the two sizes across the two positions.
In 1994, the front and rear side marker bulb sizes are reversed relative to 1993: the front takes a 194 while the rear takes a 168, whereas in 1993 the front uses a 168 and the rear uses a 194.
Because the 194 and 168 share a T10 base, substituting one for the other is physically possible, though the wattage difference means the installed bulb would not match the original electrical specification.
