The Toyota Mark II front and rear side marker bulbs both utilize a 97 bulb size across all configurations. The replacement chart covers 1972 to 1976 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 Toyota Mark II uses the 97 bulb for both front and rear side marker positions across all listed model years, 1972-1976.
The 97 is an ANSI-standardized bulb recognized in the United States and Canada, operating at 12 volts with a 13-watt output.
It is a single-filament bulb, meaning it serves one lighting function rather than combining, for example, stop and tail functions in a shared housing.
The 97 uses a BA15s bayonet base, a single-contact fitting where the bulb locks into its socket with a twist rather than a threaded or wedge-style connection.
The 97 is classified as a variant of the 1156 bulb, which shares the same BA15s base type but differs in wattage; the 1156 is rated at approximately 26.9 watts, making the 97 a lower-output alternative.
Because the 97 and 1156 share the same base, physical fitment into a BA15s socket is possible for both, but the difference in wattage means they are not electrically interchangeable without consideration of the circuit's intended load.
