Additional Notes

The 1156 is the specified back up light bulb for the Merkur Scorpio across the 1988-1989 model years.
The 1156 follows the ANSI standard, making it a recognized specification within the United States and Canada.
This bulb operates on a 12-volt electrical system and carries a 21-watt power rating, which is typical for incandescent reverse light applications.
The 1156 is a single-filament bulb, meaning it serves one lighting function rather than switching between two brightness levels.
It uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and rotated to lock into the socket.
