Ford Aspire front and rear turn signal bulbs utilize a 1156 size across both locations. The replacement chart covers vehicle production spanning 1994 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Aspire (1994-1997) uses the 1156 bulb for both the front and rear turn signals across all model years covered in these specifications.
The 1156 is a single-filament bulb, meaning it is dedicated to one lighting function rather than serving dual purposes such as combined stop and turn signal operation.
The 1156 operates at 12 volts and 21 watts, which is consistent with standard automotive electrical systems of that era.
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 in other bulb types.
The 1156 carries ANSI standardization and is recognized in both the United States and Canada, reflecting its broad compatibility within North American automotive applications.
Because the Ford Aspire uses the same 1156 bulb in all four turn signal positions, front and rear, a single bulb type covers the full turn signal circuit on the vehicle.
The BA15s bayonet base of the 1156 is not interchangeable with dual-contact bayonet bases such as the BA15d, and substituting a dual-contact bulb in a single-contact socket would result in an improper fit.
The 1156 should not be confused with the visually similar 1157, which is a dual-filament bulb with a BA15d base and is used in applications requiring both stop and turn signal functions from a single bulb.
