Additional Notes

The 1156 is the sole back up light bulb size listed across all model years of the Toyota Cressida covered by these specifications, spanning 1978-1992.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics conform to a defined North American standard used in both the United States and Canada.
The 1156 operates on a 12-volt electrical system and draws 21 watts, which is consistent with standard automotive reverse lighting applications.
The bulb uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin. This base type is not interchangeable with the BA15d double-contact bayonet base, which carries a different pin configuration.
As a single-filament bulb, the 1156 serves one dedicated function per housing. This contrasts with dual-filament types such as the 1157, which support two brightness levels within a single bulb.
The Toyota Cressida (1978-1992) uses the same 1156 bulb size for back up lights across all listed years, indicating a consistent lamp socket specification throughout the vehicle's production run covered here.
