Oldsmobile Toronado Map Light Bulb Size

Additional Notes

• The Oldsmobile Toronado map light uses five distinct bulb types across its production span: the 562, 1004, 912, 194, and 212-2, all of which conform to ANSI standards recognized in both the United States and Canada.
• The 562 festoon bulb is the most frequently specified type in the later model years, covering the Oldsmobile Toronado from 1987 through 1992, with the exception of 1988, 1989, and 1991 being continuous with 1990 and 1992. It operates at 12V and 12W and uses end-cap contacts on a 44mm-length housing.
• The 1004 is the most widely used bulb across the mid-era Toronado, appearing in model years 1975, 1977, 1978, 1980, 1982, 1983, and 1985. It features a BAY15d bayonet base and a dual-filament design rated at 12V with a 21/5W output, making it a variant of the more common 1157 bulb.
• Because the 1004 is a dual-filament bulb, it is not directly interchangeable with single-filament alternatives without accounting for the difference in filament configuration, even when physical fitment may otherwise be compatible.
• The 212-2 festoon bulb was specified for the Toronado from 1966-1969. It uses an SV8.5 base on a 41mm-length housing and operates at 12V and 12W, distinguishing it from the 562 festoon bulb, which shares the same wattage but has a longer 44mm housing and end-cap contacts rather than an SV8.5 base.
• The physical difference between the 562 and 212-2 festoon bulbs, specifically the 3mm length variation and the differing base types, means the two are not interchangeable despite sharing identical voltage and wattage ratings.
• The 1984 Toronado is the only model year in the specifications to use the 912 wedge bulb, a T15-type variant of the 921, rated at 12V and 12W. Its wedge base design differs fundamentally from the bayonet and festoon types used in surrounding model years.
• The 1971 Toronado uses the 194 miniature wedge bulb, a T10-type rated at 12V and 3.78W. At under 4W, it draws considerably less power than any other bulb type listed in these specifications.
• The shift from the 212-2 festoon type in 1966-1969 to the 194 wedge type in 1971 represents a change in both base design and power draw for the Toronado map light position.
• The 1984 model year stands as an isolated case within the 1980-1985 range, using the 912 wedge bulb rather than the 1004 bayonet type that surrounds it in adjacent years.
