Additional Notes

The 1003 is an ANSI-standardized bulb used in the United States and Canada, operating at 12 volts with a 21-watt output through a single filament.
The 1003 uses a BA15s bayonet base, which is a single-contact bayonet fitting. This base type is not interchangeable with double-contact bayonet variants such as the BA15d, and substituting an incorrect base type will result in a fitment failure.
The Ford Capri (1962-1964) uses the 1003 bulb size across all listed model years for the map light position.
