Hyundai Scoupe Back Up Light Bulb Size

Additional Notes

• The 1156 is the sole bulb type listed for the back up light position across all Hyundai Scoupe model years covered in these specifications, spanning 1991-1995.
• The 1156 bulb operates on a 12-volt electrical system and draws 21 watts, placing it in the mid-range of standard automotive incandescent output for single-filament applications.
• A single-filament design means the 1156 serves one dedicated lighting function, as opposed to dual-filament bulbs that handle two functions such as braking and running light duties simultaneously.
• The BA15s bayonet base is a single-contact fitting, where the "s" denotes a single pin. This distinguishes it from the BA15d, which carries two contact pins and is not interchangeable with the BA15s socket.
• The 1156 carries ANSI standardization applicable in both the United States and Canada, meaning the bulb conforms to a defined set of electrical and physical tolerances recognized across North American markets.
• Because the BA15s base is a specific contact configuration, substituting a visually similar bulb with a different base type would result in an incompatible fit regardless of voltage or wattage ratings.
