Additional Notes

The Daihatsu Charade uses the 1156 bulb for its back up light across the 1988-1992 model years.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are defined by a recognized North American standard used in 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, distinguishing it from double-contact bayonet variants that are not interchangeable with it.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that can serve two functions such as braking and running light simultaneously.
Because the BA15s base has only one contact pin, substituting a dual-contact bayonet bulb such as the 1157 would result in an incompatible fit despite the similar base size.
