The Volvo ACL front and rear turn signal bulbs both use a 1156 size. The replacement chart covers 1996 to 1997 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 is the sole bulb type specified for the Volvo ACL across both front and rear turn signal positions for the 1996-1997 model years.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, which suits dedicated turn signal circuits that do not share a filament with a separate running or brake light function.
The 1156 operates at 12 volts and draws 21 watts, placing it within the standard range for automotive turn signal applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, as opposed to the dual-pin BA15d variant. These two base types are not interchangeable despite their similar appearance.
The 1156 conforms to ANSI standards applicable in the United States and Canada, indicating the bulb meets regulated performance and dimensional criteria for those markets.
The front and rear turn signal positions on the Volvo ACL share the same 1156 bulb specification for both listed model years, meaning a single bulb type services all four turn signal sockets on the vehicle.
