The Dodge D100 uses a 194 bulb size for both front and rear side marker applications. The replacement chart covers 1975 to 1989 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 194 bulb is the sole bulb size specified for both the front and rear side marker positions on the Dodge D100 across all listed model years.
The 194 bulb conforms to the ANSI standard recognized in both the United States and Canada, classifying it as a regulated, standardized automotive lamp type.
This bulb follows the T10 miniature wedge form factor, which uses a tapered plastic base that presses directly into a socket without requiring a separate locking mechanism or bayonet pins.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of marker and courtesy lighting applications.
The front side marker position on the Dodge D100 uses the 194 bulb across the 1975-1979 and 1984-1989 model years.
The rear side marker position specifies the 194 bulb for the 1986-1989 model years.
Because both the front and rear side marker positions share the same 194 bulb specification, the same lamp unit serves both locations on the vehicle.
The T10 wedge base format of the 194 is shared by several other bulb numbers in the miniature wedge family, though wattage and voltage ratings differ between them, making socket compatibility alone an insufficient basis for substitution.
