Mazda 626 front and rear turn signal bulbs utilize 1034NA, 1157NA, 1156, and 1157 sizes depending on position and model generation. The replacement chart covers 1979 through 2002 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 626 front turn signal draws from three distinct bulb types across its production span: the single-filament 1156, the dual-filament 1157, and the natural amber variants 1157NA and 1034NA.
The 1157 and 1157NA are dual-filament bulbs rated at 12V and 21W/5W, using a BAY15d bayonet base. The two filaments serve separate functions, with the lower-wattage filament typically acting as a parking or position light and the higher-wattage filament serving the turn signal function.
The 1034NA is also a dual-filament bulb with a BAY15d base, rated at 12V and 21/5W, and is described as a variant of the 1157. Its natural amber glass produces a colored output without relying on an amber-tinted lens.
The 1156 and 1156NA are single-filament bulbs rated at 12V and 21W, using a BA15s bayonet base. The BA15s base differs from the BAY15d base in pin alignment, making single-filament and dual-filament bulbs physically non-interchangeable despite their similar appearance.
The Mazda 626 rear turn signal uses the 1156NA exclusively from 1993-2002, indicating that natural amber glass was a consistent rear fitment requirement during that period.
The 1157NA and 1034NA used in the front positions share the same BAY15d base as the standard 1157, but their natural amber glass coating means they are not direct visual equivalents to the clear-glass 1157 when used behind a clear or white lens.
For the 1992 Mazda 626, the front turn signal takes a 1034NA while the rear takes a 1157, meaning the front position uses a dual-filament amber variant and the rear uses a standard dual-filament clear bulb, representing a reversal of the more common pattern seen in surrounding years.
The front and rear turn signals of the Mazda 626 do not consistently share the same bulb type, and substituting one position's bulb into the other without confirming base type and filament count risks an incorrect fitment.
From 1979-1984, both the front and rear turn signals of the Mazda 626 used the 1157, a dual-filament clear bulb with a BAY15d base, representing the only years where front and rear specifications were identical across the full dataset.
The natural amber glass on the NA-suffix bulbs is a factory-specified characteristic, not an aftermarket modification, and its presence in the specifications reflects an OEM requirement tied to specific model years rather than a universal standard across the 626 lineup.
