The Mazda RX-2 front and rear side marker bulbs both utilize a 97 bulb size. The replacement chart covers 1973 to 1974 vehicle 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 Mazda RX-2 uses the ANSI 97 bulb for both front and rear side marker positions across the 1973-1974 model years.
The 97 bulb is a single-filament type, meaning it serves only one lighting function rather than combining two, such as stop and tail.
It operates on a 12-volt electrical system and draws 13 watts, which is consistent with standard automotive low-current marker lighting of that era.
The 97 bulb uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin rather than the dual-pin BA15d configuration.
The 97 is classified as a variant of the more widely produced 1156 bulb, sharing the same BA15s base type but differing in wattage output.
Because the 97 and 1156 share the same base, physical fitment into the socket is possible with either bulb, though their wattage ratings differ and substitution may affect circuit behavior.
The ANSI designation confirms the 97 bulb conforms to standardized specifications recognized in both the United States and Canada.
The uniform use of a single bulb type across all four side marker positions on the RX-2 means front and rear sockets accept the same replacement bulb.
