Additional Notes

The Suzuki Motorcycle LT125 uses the type 81 bulb for its tail light across the 1983-1987 model years.
The type 81 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts and 8 watts.
As a single-filament bulb, the type 81 serves one lighting function only, which in this application is the tail light.
The type 81 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, distinguishing it from dual-contact bayonet variants that are not interchangeable with this socket.
