Additional Notes

The 1157 is the sole brake bulb type listed for the Toyota Crown across the 1969-1972 model years.
The 1157 is an ANSI-standardized bulb designation used in the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters recognized across North American markets.
The 1157 is a dual-filament bulb, which allows it to serve two lighting functions within a single unit. In brake light applications, the higher-wattage filament activates under braking while the lower-wattage filament handles a secondary function such as running or tail light duty.
The bulb operates at 12 volts with a wattage rating of 21W for the primary filament and 5W for the secondary filament, reflecting the standard electrical system voltage common to passenger vehicles of that era.
The 1157 uses a BAY15d bayonet base, which is a double-contact base with offset pins. The offset pin arrangement is a deliberate fitment control, as it prevents the bulb from being inserted in the wrong orientation, which would cause the two filaments to activate incorrectly.
Because the BAY15d base uses offset pins, it is not interchangeable with single-contact bayonet bases or double-contact bases with symmetrical pin placement, such as the BA15d, despite their physical similarity.
