Additional Notes

The 1157 bulb is the parking light specification for the Toyota Corona across the 1969-1981 model years, making it the dominant bulb type in this fitment range.
The 1157 is a dual-filament bulb rated at 12V with a 21W/5W output, meaning it carries separate filaments for two distinct brightness levels within a single housing.
The 1157 uses a BAY15d bayonet base, which is an offset twin-pin mount. This base design prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
For the 1982 Toyota Corona, the parking light specification shifts to the 194 bulb, which is a single-filament miniature wedge type rated at 12V and 3.78W.
The 194 uses a T10 wedge base, which is a pinless design that relies on spring tension from the socket to hold the bulb in place, rather than a locking bayonet mechanism.
The 194 and 1157 are not interchangeable. Their base types, wattage ratings, and filament configurations are fundamentally different, and neither bulb is physically compatible with the other's socket.
Both the 194 and 1157 are ANSI-standardized bulbs recognized in the US and Canadian markets, meaning their electrical and physical specifications conform to a defined industry standard rather than a proprietary format.
