Additional Notes

The bulb size 90 is an ANSI-standard type recognized in both the United States and Canada.
The Pontiac J2000 uses the 90 bulb for the map light across its 1982-1983 model years.
The 90 bulb operates on a 12-volt electrical system and draws 13 watts.
A single-filament design means the 90 bulb serves one lighting function rather than combining two, such as stop and tail.
The BA15s bayonet base features a single locating pin on the base collar, which distinguishes it from the dual-pin BA15d variant and makes the two types non-interchangeable.
