Dodge 600 front and rear side marker bulb sizes include 194NA, 168, and 2057 bulb options for this vehicle model. The replacement chart covers 1983 to 1988 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 Dodge 600 front side marker uses two distinct bulb types across its production years, with the 1983-1985 models fitted with the 168 bulb and the 1987-1988 models fitted with the 194NA bulb.
The 194NA is a natural amber glass miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W under the ANSI standard applicable in both the US and Canada.
The 168 bulb is also a T10 miniature wedge type, rated at 12V and 4.9W, making it slightly higher in wattage than the 194NA despite sharing the same base form factor.
Because the 194NA and 168 share the T10 wedge base, they are physically interchangeable in terms of fitment, though the 194NA incorporates natural amber glass coloring that the 168 does not, which affects the emitted light color.
The rear side marker of the Dodge 600 uses the 168 bulb for the 1984-1988 model years, consistent with the same T10 wedge specification described above.
The 1983 Dodge 600 rear side marker is fitted with the 2057 bulb, which differs substantially from the 168 in both base type and function, using a BAY15d bayonet base rather than a wedge mount.
The 2057 is a dual-filament bulb rated at 12V with a 26.9W high filament and an 8W low filament, placing it in a significantly higher power class than either the 168 or 194NA.
The 2057 is noted as a brighter variant of the 1157, sharing the same BAY15d bayonet base, which means the two are physically interchangeable in base fitment, though their output levels differ.
The BAY15d base of the 2057 is not compatible with the T10 wedge socket used by the 168, meaning the 1983 rear side marker housing is not interchangeable with the housings used in the 1984-1988 rear side marker positions.
