Additional Notes

The 1003 bulb is specified for the Ford Maverick map light across the 1974-1976 model years, making it the more frequently listed bulb type in these specifications.
The 212-2 festoon bulb is specified for the 1977 Ford Maverick map light, representing a change from the bulb type used in prior model years.
The 212-2 is a festoon-style bulb measuring 41mm in length with an SV8.5 base, operating at 12 volts and 12 watts.
The 1003 is a single-filament bulb with a BA15s bayonet base, operating at 12 volts and 21 watts.
The BA15s bayonet base of the 1003 bulb features a single contact point at the base, which is a defining characteristic of the BA15s designation and distinguishes it from dual-contact bayonet variants.
The 1003 draws 21 watts, while the 212-2 draws 12 watts, meaning the two bulb types are not electrically equivalent and are not interchangeable between model years.
The festoon form of the 212-2 requires a holder that grips both ends of the bulb, a mounting style that is physically incompatible with the bayonet socket used by the 1003.
Both bulb types conform to ANSI standards applicable in the United States and Canada.
