Volvo 164 front and rear side marker bulbs utilize 257, 89, and 57 bulb sizes depending on location and model variant. The replacement chart covers 1969 through 1975 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo 164 side marker bulb specifications cover model years 1969-1975 across both front and rear positions.
Three distinct ANSI-standard bulb types appear across these specifications: the 257, the 89, and the 57, each carrying different base types and wattage ratings.
The 89 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 13W. It is a lower-wattage variant of the 1156 bulb family.
The 257 bulb is rated at 12V and 2W, and it accepts either a festoon or BA9s base configuration, making it a low-power instrument-style bulb.
The 57 bulb is a single-filament type with a BA9s base, rated at 12V and 1W, representing the lowest wattage of the three bulb types in these specifications.
The Volvo 164 used the 89 bulb in both the front and rear side marker positions for model years 1969-1972, indicating a consistent fitment across those four years.
For model years 1973-1975, the front side marker position transitioned to the 257 bulb, which operates at a significantly lower wattage than the 89 it replaced.
The rear side marker position for the 1973 model year uses the 57 bulb rather than the 257 used in 1974-1975, meaning the front and rear positions do not share the same bulb type for that year.
The 257 and 57 bulbs both use a BA9s base, but they are not interchangeable due to their different wattage ratings and physical form factors, as the 257 also supports a festoon configuration.
The BA15s bayonet base of the 89 bulb is physically incompatible with the BA9s base of the 257 and 57 bulbs, so substitution between these types is not possible without a socket adapter.
