Dodge Monaco front and rear side marker bulbs utilize 194, 168, 1034NA, and 67 bulb sizes depending on location and model generation. The replacement chart covers vehicle production spanning 1968 to 1992 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 T10 wedge base is the most frequently specified bulb form factor across the Dodge Monaco's side marker history, covering both the 194 and 168 bulb types. Both share the same T10 miniature wedge base and operate at 12V, though the 168 draws 4.9W compared to the 194's 3.78W, making them physically similar but electrically distinct and not directly interchangeable without consideration of wattage differences.
The Dodge Monaco uses the 194 bulb for both front and rear side markers across the 1990-1992 model years, as well as in 1972, representing the lowest wattage T10 wedge option in the specifications at 3.78W.
The 168 bulb is specified for both front and rear side markers across the 1973-1976 and 1978 model years on the rear, and the same years on the front with one exception. Both positions share identical 168 fitment for 1973-1976 and 1978.
The 1977 front side marker is the only position in the entire specification set to use the 1034NA bulb. This bulb carries a BAY15d bayonet base and dual-filament construction, making it a fundamentally different fitment from all other years, which use either wedge-base or single-filament bayonet bulbs.
The 1034NA is a natural amber glass variant of the 1157 family, rated at 21/5W with a dual-filament design. Its BAY15d base is physically incompatible with the T10 wedge sockets used in surrounding model years, meaning a direct substitution with the 168 or 194 is not possible without a socket adapter.
The 1977 rear side marker reverts to the 168 bulb while the front uses the 1034NA, making 1977 the only model year in the specifications where the front and rear side marker bulbs differ from each other.
The 67 bulb is specified for both front and rear side markers across the 1969-1971 model years. It uses a BA15s single-contact bayonet base and is rated at 12V, 8W, placing it in the same bayonet family as the 1156 but at a lower wattage.
The 1895 bulb, a T5 miniature wedge type rated at only 0.9W, is specified for both front and rear side markers on the 1968 Dodge Monaco. It operates at a substantially lower wattage than any other bulb in the specification set and uses a smaller T5 wedge form factor rather than the T10 base found in later years.
The transition from the T5 1895 bulb in 1968 to the BA15s bayonet 67 bulb in 1969 represents a base type change, meaning the socket design in the vehicle changed between those model years. Similarly, the shift from the 67 in 1971 to the 194 in 1972 marks another base type change, from bayonet to T10 wedge.
All bulb types listed across the Dodge Monaco side marker specifications conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical ratings across the full range of fitments.
