Additional Notes

The 1003 is an ANSI-standard bulb recognized in both the United States and Canada, operating at 12 volts with a 21-watt output through a single filament.
The 1003 bulb uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm base width. The single-contact design means only one electrical connection is made at the base, consistent with its single-filament construction.
The Dodge A100 Pickup uses the 1003 bulb for the dome light across the 1967-1968 model years.
