Dodge Colt front and rear side marker bulb sizes include 1157, 194, 168, and 158 specifications across different model configurations. The replacement chart covers 1971 to 1994 production years with corresponding bulb size data.
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 most frequently specified size across the Dodge Colt's side marker positions, appearing in both front and rear applications across the 1971-1972 and 1979-1985 model years.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, operating on a single filament within a wedge-style base that requires no separate socket retainer.
The 168 bulb shares the same T10 miniature wedge form factor as the 194 but draws slightly more power at 4.9W, making the two physically interchangeable in housing terms while differing in output.
The 1157 is a dual-filament bulb with a BAY15d bayonet base rated at 12V and 21W/5W, a construction fundamentally different from the T10 wedge types used elsewhere in the Dodge Colt's side marker system.
For the 1993-1994 Dodge Colt, the front side marker uses the 1157 while the rear uses the 168, meaning the front and rear positions are not interchangeable despite both being side marker functions.
The 1992 Dodge Colt presents a headlamp-count dependency: vehicles with 2 headlamps use the 194 for both front and rear side markers, while vehicles with 4 headlamps use the 168 for both positions.
The 158 bulb, a T10 wedge type rated at 12V and 3W, is the lowest-wattage bulb in these specifications and is exclusive to the 1973 model year for both front and rear side marker positions.
All four bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical ratings across the range.
The BAY15d bayonet base of the 1157 uses offset pins to prevent incorrect insertion, a feature absent from the wedge-base bulbs such as the 194, 168, and 158.
Because the 194 and 168 share the T10 wedge form factor, physical fitment in the socket is possible for either type, though the wattage difference means they are not rated equivalents for the specified application.
