The Dodge D150 front and rear side marker bulbs both utilize a 194 bulb size for optimal lighting performance. The replacement chart covers vehicle production spanning 1977 to 1993, detailing bulb specifications across the model's manufacturing timeline.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge D150 uses the 194 bulb for both front and rear side marker positions across all listed model years.
The 194 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts with a power draw of 3.78 watts.
The 194 bulb follows the T10 miniature wedge form factor, a designation that refers to its tubular glass envelope and wedge-style base, which requires no separate metal socket pins.
The front side marker of the Dodge D150 uses the 194 bulb across the 1977-1993 model years.
The rear side marker position uses the same 194 bulb, with coverage spanning the 1986-1991 model years.
Because both the front and rear side marker positions share the same bulb specification, a single 194 bulb type serves all side marker applications listed for this vehicle.
The T10 wedge base is a push-in fitment, meaning the bulb is retained by friction within its housing rather than by a bayonet or screw mechanism, which is a relevant consideration during replacement.
At 3.78 watts on a 12-volt circuit, the 194 draws approximately 0.315 amperes, placing it in the low-current category typical of marker and courtesy lighting applications.
