The Volvo 265 front turn signal uses bulb sizes 1156, 1034NA, or 1157NA, while the rear turn signal requires a 1156 size bulb. 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 bulb is the most frequently specified type across the Volvo 265 turn signal data, appearing in the rear turn signal position for all model years from 1976-1981 and in the front turn signal position for 1976, 1977, and 1981.
The 1156 is an ANSI-standard single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, which accepts only single-filament applications.
The front turn signal of the Volvo 265 used three different bulb types across its production run, while the rear turn signal position remained consistent with the 1156 throughout the same period.
The 1157NA, specified for the front turn signal in 1978-1979, is a dual-filament bulb rated at 12V with a 21W main filament and a 5W secondary filament, fitted with a BAY15d bayonet base.
The BAY15d base used by the 1157NA features offset pins to prevent incorrect insertion, distinguishing it physically from the BA15s base of the 1156, which means the two types are not interchangeable.
The 1034NA, specified for the front turn signal in 1980, shares the same BAY15d bayonet base and dual-filament construction as the 1157NA and is classified as a variant of the 1157 type.
Both the 1034NA and 1157NA feature natural amber glass, which produces a colored output without relying on a painted or coated lens to achieve the amber signal color.
The 1034NA and 1157NA carry identical voltage and wattage ratings of 12V, 21W/5W, reflecting their shared dual-filament design despite being distinct ANSI part numbers.
Because the front turn signal position transitioned from the dual-filament 1157NA in 1979 to the 1156 single-filament type in 1981, substituting one for the other in those positions would involve a base type mismatch and a filament count difference.
