Volvo 164 front and rear turn signal bulbs both use 1156 size bulbs for proper operation. The replacement chart covers vehicle production spanning 1969 to 1975 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 Volvo 164 uses the 1156 bulb for both the front and rear turn signals across all model years from 1969-1975.
The 1156 is a single-filament bulb, meaning it is dedicated to one lighting function rather than serving dual purposes such as combining turn signal and brake light duties.
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 mount where the bulb is inserted and twisted to lock into place.
The 1156 is an ANSI-standardized bulb, recognized across the United States and Canada under a common designation system.
Because the Volvo 164 uses the same 1156 bulb for both front and rear turn signal positions across all listed model years, the two positions are interchangeable with one another in terms of bulb fitment.
