Mazda 323 front and rear side marker bulbs utilize 1157, 194, or 168 size configurations. The replacement chart covers 1986 to 1994 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 Mazda 323 side marker bulb specifications cover three distinct bulb types across the model's production years: the 1157, 194, and 168.
The 1157 is a dual-filament bulb rated at 12V with a 21W/5W output and a BAY15d bayonet base. Its dual-filament design means it supports two separate brightness levels within a single housing, which distinguishes it from the single-filament bulbs also present in these specifications.
The 194 and 168 are both miniature wedge bulbs of the T10 form factor operating at 12V. Despite sharing the same base type and physical form, they carry different wattage ratings: 3.78W for the 194 and 4.9W for the 168. These two bulbs are not interchangeable without accounting for that wattage difference.
For the Mazda 323, the 1157 appears in both the front and rear side marker positions for the 1993-1994 model years, making it the most recently specified bulb type across both positions in this dataset.
The 168 bulb is the most widely used type across the 323's side marker specifications, covering the front position for 1986-1989 and the rear position for 1986-1991.
The 1992 model year uses the 194 bulb in both the front and rear side marker positions. This places the 194 as a transitional specification between the 168 used in earlier years and the 1157 adopted for 1993-1994.
The BAY15d bayonet base of the 1157 is physically and electrically incompatible with the wedge-style socket required by the 194 and 168. A vehicle fitted for one base type cannot accept a bulb of the other without socket modification.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical tolerances across the range.
