Additional Notes

The Volvo 262 uses the 1156 bulb across all listed model years for the back up light position.
The years covered by these specifications span 1976 and 1978-1981.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics conform to a defined North American standard used in both the United States and Canada.
The 1156 operates on a 12-volt electrical system and draws 21 watts, which is typical of a single-filament incandescent automotive bulb used in a dedicated switching function such as reverse lighting.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a single-contact bayonet fitting with a 15mm base width. The single-contact design corresponds directly to the single-filament construction of the bulb.
Because the 1156 is a single-filament bulb, it serves one lighting function only. It is not interchangeable with dual-filament variants such as the 1157, which shares a similar bayonet base style but carries two contacts and two filaments for separate functions.
