Additional Notes

The Toyota MR2 uses the 1157 bulb size for the parking light across the 1985-1989 and 1991-1995 model years.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope, one rated at 21W and the other at 5W.
The bulb operates on a 12-volt electrical system, which is standard for passenger vehicles of this type.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation by ensuring the pins are not symmetrically placed.
The 1157 conforms to ANSI standards and is specified for use in the United States and Canada, indicating it meets North American automotive lighting requirements.
Because the 1157 is a dual-filament bulb, it is capable of serving two lighting functions from a single socket, which is why it is commonly found in positions that combine parking and brake light duties.
The BAY15d base of the 1157 is not interchangeable with single-filament bayonet bases such as the BA15s, as the offset pin configuration and filament count differ between the two types.
