Mazda 929 front and rear side marker bulbs utilize 168, 194, and 1157 bulb sizes depending on location and model variation. The replacement chart covers 1988 to 1995 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 929 front side marker uses the 168 bulb across most of its production span, specifically for the 1988-1991 and 1993-1995 model years.
The 168 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W, and is recognized for use in both the United States and Canada.
The 194 bulb also follows the T10 wedge form factor but draws less power at 3.78W, making it a lower-wattage variant within the same physical family as the 168.
Although the 168 and 194 share the T10 wedge base, their wattage ratings differ, and the two are not electrically identical despite their physical similarities.
The 1992 Mazda 929 is the only model year in which the 194 bulb is specified for both the front and rear side marker positions.
The rear side marker specification shifts to the 1157 bulb for the 1993-1995 model years, representing a significant change in bulb type from earlier years.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W high filament and a 5W low filament, which is a fundamentally different construction from the single-filament T10 wedge types used elsewhere in these specifications.
The BAY15d bayonet base of the 1157 is physically incompatible with the T10 wedge sockets used by the 168 and 194, meaning the rear side marker housings for 1993-1995 are not interchangeable with those from earlier model years.
For the 1991 model year, the front and rear side markers both use the 168 bulb, while the 1992 model year uses the 194 in both positions, indicating a socket-level distinction between those two years.
The 1157 bulb's dual-filament design is typically associated with combined stop and tail light functions, and its presence in the rear side marker position of the 1993-1995 929 reflects a specific engineering choice for that application.
