Additional Notes

The Polaris Sprint uses the ANSI 90 bulb for its brake light function across the 1986-1990 model years.
The ANSI 90 is a single-filament bulb, meaning it serves one lighting function only, which in this application is the brake light.
The 90 bulb operates on a 12-volt electrical system and draws 13 watts of power.
It uses a BA15s bayonet base, which is a single-contact bayonet fitting with a 15mm base width. The single-contact design corresponds directly to the single-filament construction of the bulb.
The ANSI 90 designation indicates the bulb meets standardized specifications recognized in both the United States and Canada.
Because the BA15s base is a single-contact fitting, it is not interchangeable with BA15d bases, which carry two contacts and are used in dual-filament applications.
