Mazda 929 front turn signal bulbs utilize 1034NA, 1157NA, or 1157 sizes, while rear turn signal bulbs use 1156 or 1157 sizes. The replacement chart covers 1988 through 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 1156 bulb is the most frequently specified type across the Mazda 929 turn signal positions, appearing in the front signal from 1988-1991 and in the rear signal from 1988-1991 and 1993-1995. It is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base.
The 1157 is a dual-filament bulb rated at 12V and 21W/5W, using a BAY15d bayonet base. Its two filaments serve separate functions within a single housing, which physically distinguishes it from the single-filament 1156 despite both using bayonet-style bases.
The BAY15d base used by the 1157, 1157NA, and 1034NA features offset locating pins, which prevents these dual-filament bulbs from being inserted into a BA15s socket designed for the single-filament 1156. The two base types are not interchangeable.
The 1034NA is described as a variant of the 1157. Both share the BAY15d base and 12V/21W/5W ratings, but the 1034NA is distinguished by natural amber glass rather than a clear envelope.
The 1157NA shares the same base, voltage, and wattage as the 1157 but also features natural amber glass, placing it in the same amber-glass category as the 1034NA.
Natural amber glass, present in the 1034NA and 1157NA, produces amber-colored light without relying on a colored lens. In applications where the housing lens is clear, these bulbs fulfill amber turn signal output requirements directly from the bulb itself.
The front turn signal of the Mazda 929 changed bulb types across model years, with the 1156 used from 1988-1991, the 1034NA in 1993 and 1995, the 1157 in 1992, and the 1157NA in 1994. These are not interchangeable due to differing base types and filament configurations.
The rear turn signal of the Mazda 929 used the 1157 in 1992 and the 1156 in all other listed model years. The shift between these two types reflects a change in base and filament configuration for that model year.
All four bulb types listed are ANSI standards applicable to the United States and Canada, meaning they conform to a defined set of electrical and physical specifications recognized across North American automotive applications.
In 1992, the Mazda 929 specified the 1157 for both the front and rear turn signals, making it the only model year in the listed specifications where both positions shared the same dual-filament, clear-glass BAY15d bulb.
