Volvo 262 front turn signal bulbs use 1156 or 1157NA size, while rear turn signal bulbs use 1156 size. The replacement chart covers 1976 through 1981 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 1156 is a single-filament bulb operating at 12V and 21W, fitted with a BA15s bayonet base. It conforms to the ANSI standard used in the United States and Canada.
The 1157NA is a dual-filament bulb rated at 12V with a 21W/5W output split between its two filaments. It uses a BAY15d bayonet base and features natural amber glass, also conforming to the ANSI standard for the US and Canadian markets.
The BAY15d base of the 1157NA differs from the BA15s base of the 1156. These two base types are not interchangeable, as the BAY15d has offset locating pins to prevent incorrect installation.
The Volvo 262 rear turn signal position uses the 1156 bulb across all model years listed, spanning 1976-1981.
The front turn signal position uses the 1157NA for the 1979-1980 model years, while the 1156 is specified for 1976, 1978, and 1981.
The natural amber glass of the 1157NA produces a colored output directly from the bulb itself, rather than relying on a tinted lens to achieve the amber signal color.
The dual-filament design of the 1157NA allows a single bulb to serve two functions, with the lower 5W filament typically used for a running or parking light and the higher 21W filament activated for the turn signal.
Because the 1156 is a single-filament bulb, it serves only one function per socket, which corresponds to its exclusive use in the rear turn signal positions across all listed model years of the Volvo 262.
