Bulb Size by Year Range

Description	Bulb Size
ANSI standard (US & Canada). Single-filament bulb with BA15s bayonet base. 12V, 21W.	1156
ANSI standard (US & Canada). Single-filament bulb with BA15s bayonet base. Variant of 1156. 12V, 21W.	199

The 1156 and 199 are the two bulb types specified for the Dodge B200 backup light across the 1972-1980 model years.
Both the 1156 and 199 are ANSI-standardized bulbs recognized in the US and Canada, each operating at 12 volts with a 21-watt output.
Each bulb type uses a BA15s bayonet base, a single-contact base design where the bulb locks into the socket with a twist.
Both bulbs are single-filament types, meaning each serves one lighting function rather than switching between two brightness levels.
The 199 is classified as a variant of the 1156, sharing the same voltage, wattage, and BA15s base configuration.
The Dodge B200 used the 1156 in 1972, 1974, 1976, 1979, and 1980, while the 199 was specified for 1973, 1975, 1977, and 1978.
Because the 199 is a variant of the 1156 with identical electrical and base specifications, the two bulbs share a high degree of physical and functional similarity, though fitment interchangeability is not explicitly confirmed in the specifications.
