Additional Notes

The Ford Granada map light specifications cover model years 1975-1982, with three distinct bulb types used across that span: the 105, the 211-2, and the 1003.
The 211-2 is the most frequently specified bulb across these years, appearing in 1977-1978 and 1980. It is a festoon-style bulb with a 41mm length and an SV8.5 base, rated at 12V and 12W.
The 1003 bulb is specified for 1975-1976 and 1979. It uses a BA15s bayonet base and is rated at 12V and 21W, making it the highest-wattage option among the three types listed.
The 105 bulb is specified for 1981-1982. Like the 1003, it uses a BA15s bayonet base, but it draws only 13W at 12V, making it a lower-wattage single-filament bulb by comparison.
Although the 105 and 1003 share the same BA15s bayonet base, their wattage ratings differ significantly at 13W and 21W respectively. This difference means the two types are not interchangeable despite the physical base compatibility.
The 211-2 festoon bulb uses an SV8.5 base, a contact type that is physically distinct from the BA15s bayonet base used by both the 105 and the 1003, making cross-substitution between festoon and bayonet types mechanically incompatible.
All three bulb types conform to ANSI standards recognized in both the United States and Canada, indicating standardized electrical and physical tolerances across the Ford Granada map light fitments listed.
The 105 bulb is described as a variant of the 1156, a widely used automotive bulb. Despite this relationship, the 105 operates at 13W rather than the 1156's typical 26.9W rating, so the two are not equivalent substitutes.
