Additional Notes

The Toyota Corona uses the 1157 bulb for the tail light position across all listed model years, spanning 1969-1982.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single housing, typically combining stop light and tail light operation at different brightness levels.
The 1157 operates at 12 volts with a wattage rating of 21W on the high-filament circuit and 5W on the low-filament circuit, reflecting its dual-function design.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to ensure the bulb is seated in the correct rotational position, preventing filament misalignment.
The 1157 conforms to ANSI standards and is rated for use in both the United States and Canada, indicating compliance with North American automotive lighting requirements.
Because the BAY15d base has offset pins, it is not interchangeable with single-filament bayonet bulbs that use a different pin configuration, such as the BA15s base found on the 1156 bulb type.
