The Mazda Mizer front and rear side marker bulb size is 89 for both locations. The replacement chart covers 1976 to 1977 model years with bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda Mizer uses the ANSI 89 bulb for both front and rear side marker positions across the 1976-1977 model years.
The 89 bulb operates on a 12-volt system and draws 13 watts, placing it in the low-wattage range typical of side marker applications.
It is a single-filament bulb, meaning it serves one lighting function rather than combining roles such as stop and tail into a shared unit.
The 89 uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm collar width, distinguished from dual-contact variants by its single pin offset.
The 89 is described as a lower wattage variant of the 1156 bulb, which shares the same BA15s base type but draws significantly more power, making the two non-equivalent as direct replacements despite their physical similarity.
The 89 bulb conforms to ANSI standards and is recognized in both the United States and Canada, indicating standardized electrical and physical tolerances across North American markets.
