The Volvo 145 front and rear side marker bulb sizes include 67, 97, 89, and 257 specifications for this vehicle model. The replacement chart covers 1968 to 1974 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo 145 front side marker position uses three distinct bulb sizes across its production run: the 89 for 1968-1972, the 97 for 1973, and the 67 for 1974.
The Volvo 145 rear side marker position follows a similar pattern, with the 89 fitted for 1968-1972, the 97 for 1973, and the 257 for 1974.
The 89 bulb is an ANSI-standard single-filament type with a BA15s bayonet base, rated at 12V and 13W, and is classified as a lower-wattage variant of the 1156.
The 97 bulb shares the same BA15s bayonet base and 12V, 13W rating as the 89, and is also a variant of the 1156 family, though it is a distinct part number.
The 67 bulb carries a BA15s bayonet base and operates at 12V, but draws only 8W, making it the lowest-wattage bulb among those specified for the 145 side marker positions.
The 257 bulb, used in the 1974 rear side marker position, is rated at 12V and 2W and uses either a festoon or BA9s base, making it fundamentally different in construction from the BA15s bayonet-base bulbs used in all other positions and years.
Because the 89, 97, and 67 bulbs all share the BA15s bayonet base, physical fitment across those positions may be possible, but their wattage ratings differ and direct substitution is not supported by these specifications.
The 257 bulb in the 1974 rear side marker is not interchangeable with any other bulb specified for the 145, as its base type and wattage are distinct from the rest of the fitment data.
The 1973 model year is the only year in which the front and rear side marker positions share the same bulb size, both using the 97.
