Additional Notes

The Toyota Pickup uses the 1157 bulb for brake lighting across the 1984-1995 model years, making it the most consistently specified bulb type in these fitment records.
The 1157 is a dual-filament bulb rated at 12V with a 21W/5W output and a BAY15d bayonet base, conforming to ANSI standards recognized in both the United States and Canada. The dual-filament design allows a single bulb to serve both running light and brake light functions at different wattages.
Model years 1975-1983 of the Toyota Pickup use the 1034 bulb rather than the 1157. The 1034 shares the same BAY15d bayonet base and 12V, 21/5W dual-filament configuration as the 1157, but the two are classified as distinct ANSI types and are not directly interchangeable despite their similarities.
The BAY15d bayonet base found on both the 1157 and 1034 features two offset pins at different heights, a design that prevents incorrect single-filament bulbs from being seated in a dual-filament socket.
The 1993-1995 Toyota Pickup specifies a 921 wedge bulb for the Center High Mount Stop Light. This is a separate fitment from the standard brake bulb used in the tail lamp assemblies.
The 921 is a single-filament T15 wedge bulb rated at 12V and 16W. Its wedge base differs entirely from the BAY15d bayonet base of the 1157 and 1034, meaning no cross-compatibility exists between the 921 and the other two bulb types listed in these specifications.
