Volvo 760 front and rear side marker bulbs utilize 1157NA and P21/5W sizes respectively, with the front bulb measuring 67 units. The replacement chart covers vehicle production spanning 1983 to 1990, detailing bulb size specifications across the model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo 760 front side marker uses the 1157NA bulb for the 1988-1990 model years. This bulb follows the ANSI standard used in the United States and Canada.
The 1157NA is a dual-filament bulb rated at 12V with a 21W/5W power draw. Its two filaments allow it to serve both steady-on and reduced-brightness functions within a single housing.
The 1157NA features a BAY15d bayonet base, which is an offset dual-contact base. The offset pin arrangement prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
The natural amber glass of the 1157NA produces its amber color through the glass itself rather than through a colored lens. This distinguishes it from clear-glass variants of the 1157 that rely on an external amber housing to produce the required marker color.
The 1983-1984 Volvo 760 front side marker uses the type 67 bulb instead of the 1157NA. The type 67 is a single-filament bulb rated at 12V and 8W, making it a lower-wattage design than the 1157NA.
The type 67 uses a BA15s bayonet base, which is a single-contact base with a centered pin. This base is not interchangeable with the BAY15d base found on the 1157NA, despite both being bayonet-style fittings.
The Volvo 760 rear side marker for 1988-1990 uses the P21/5W bulb. This bulb follows the ECE standard, which governs lighting regulations in Europe and many other markets worldwide.
The P21/5W is a dual-filament bulb rated at 12V with a 21W/5W output, and it also uses a BAY15d bayonet base. While its base type physically matches that of the 1157NA, the two bulbs belong to different regulatory standards and are not considered interchangeable replacements.
The front and rear side marker positions on the 1988-1990 Volvo 760 use different bulb standards despite sharing the same base type. The front uses the ANSI-standard 1157NA while the rear uses the ECE-standard P21/5W.
The 1983-1984 front side marker specification uses the type 67, while the 1988-1990 front side marker specification uses the 1157NA. These two bulbs differ in filament count, wattage, and base type, making them non-interchangeable.
