Additional Notes

The 212-2 bulb is the most frequently specified map light bulb for the Pontiac Grand Prix, covering model years 1998-2002. It is an ANSI-standard festoon bulb with a 41mm length, SV8.5 base, rated at 12V and 12W.
The 906 bulb is the second most recurring specification, appearing across model years 1988-1991 and 1995-1996. It is a T10 miniature wedge bulb rated at 12V and 8W.
The 1004 bulb is specified for several non-consecutive model years spanning 1962-1987. It is a dual-filament bulb with a BAY15d bayonet base rated at 12V and 21/5W, and is noted as a variant of the 1157.
The 211-2 bulb, specified for the 1993 model year, shares the same 41mm festoon format and SV8.5 base as the 212-2 but is a distinct ANSI part number. The two are not confirmed interchangeable within these specifications.
The 2004 model year uses the 12961, a Philips-branded T10 miniature wedge bulb with a W2.1x9.5d base rated at 12V and 5W. This is the only Philips part number present in the specifications, as all other bulbs carry ANSI designations.
The 168 bulb is specified for the 1997 and 2003 model years. Like the 906, it is a T10 miniature wedge bulb, but it operates at a lower wattage of 4.9W compared to the 906's 8W, making them electrically distinct despite sharing the same bulb format.
The 89 bulb, specified for model years 1965-1968, uses a BA15s single-contact bayonet base and is rated at 12V and 13W. It is described as a lower-wattage variant of the 1156, which uses the same base type.
The bulb number 24, specified for the 1992 and 1994 model years, uses a BA9s base and is rated at only 2W, making it the lowest-wattage bulb in these specifications. Its BA9s base is physically incompatible with the wedge, festoon, and bayonet bases used by other bulbs in this set.
Three distinct base types are present across the full range of specifications: the wedge base (T10 format, used by the 12961, 168, and 906), the SV8.5 festoon base (used by the 212-2 and 211-2), and bayonet bases (BA9s for the 24, BA15s for the 89, and BAY15d for the 1004). These base differences mean bulbs from different groups are not physically interchangeable.
The wattage range across all specified bulbs spans from 2W (bulb 24) to 21W on the high filament of the dual-filament 1004, reflecting significant variation in power draw across different model years of the Grand Prix.
