The Dodge Ramcharger front and rear side marker bulb size measures 194 for both locations. The replacement chart covers vehicle production spanning 1974 to 1993.
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 Ramcharger across all listed model years.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, classifying it as a standardized miniature wedge type within the T10 form factor.
Operating at 12 volts and 3.78 watts, the 194 is a low-wattage bulb suited to side marker applications where continuous illumination at minimal power draw is typical.
The T10 wedge base design means the bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism, which is a common trait of marker and courtesy light applications.
The front side marker position on the Dodge Ramcharger uses the 194 bulb across the 1974-1993 model years according to the specifications.
The rear side marker position on the Dodge Ramcharger uses the 194 bulb across the 1986-1991 model years according to the specifications.
Because the same 194 bulb size is specified for both the front and rear side marker positions, the bulb is interchangeable between those two locations on applicable model years.
The T10 wedge base is shared by several bulb numbers beyond the 194, including the 168 and 2825, though those alternatives carry different wattage ratings and are not specified here for this vehicle.
