Additional Notes

The 1156 is the specified back up light bulb size for the Suzuki Verona across the 2004-2006 model years.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, which in this application is the reverse light circuit.
It operates on a 12-volt electrical system and draws 21 watts, both standard figures for incandescent automotive bulbs in this role.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, distinguishing it from the dual-contact BA15d base used on other bulb types.
The 1156 carries ANSI standardization recognized in both the United States and Canada, indicating consistent manufacturing specifications across compliant products sold in those markets.
Because the BA15s base is a single-contact design, it is not interchangeable with visually similar bulbs that use a dual-contact bayonet base, such as the 1157, despite sharing the same base shell size.
