Additional Notes

The Blue Bird All American RE uses the 1156 bulb size across all model years listed in the specifications, from 2000 through 2018, for the back up light position.
The 1156 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical standards shared across manufacturers.
This bulb operates on a 12-volt system and draws 21 watts, which is typical of incandescent automotive lighting designed for standard vehicle electrical systems.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, which is consistent with its application in a dedicated back up light rather than a combined stop/tail position.
The base type is BA15s, a bayonet-style mount with a single contact pin. The "s" designation in BA15s indicates a single contact at the base, distinguishing it from the dual-contact BA15d used in two-filament applications.
Because the 1156 and the visually similar 1157 share the same BA15 bayonet housing size, the two are not interchangeable. The 1157 uses a BA15d dual-contact base and would not seat correctly in a socket wired for the single-contact BA15s configuration.
