Additional Notes

The 1156 bulb is the most frequently specified back up light bulb for the Dodge W200, appearing across the 1975-1977 and 1979-1980 model years.
The 1156 is an ANSI-standard single-filament bulb rated at 12 volts and 21 watts, fitted with a BA15s bayonet base.
A BA15s bayonet base features a single contact at the base and two side pins positioned at the same height, which locks the bulb into the socket with a push-and-twist motion.
The 1978 Dodge W200 uses the 199 bulb rather than the 1156 for the back up light position.
The 199 is classified as a variant of the 1156, sharing the same ANSI-standard single-filament design, BA15s bayonet base, 12-volt rating, and 21-watt output.
Because the 199 and 1156 share the same base type and electrical ratings, their physical and electrical compatibility is closely related, though they are catalogued as distinct part numbers.
