Volvo 245 front turn signal bulbs utilize 1034NA, 1157NA, or 1156 size configurations, while rear turn signal bulbs require 1156 size bulbs. The replacement chart covers 1975 through 1989 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 widely used type across the Volvo 245 turn signal specifications, appearing in the front position from 1975-1986 and in the rear position across all model years from 1975-1989.
The 1156 is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, and conforms to ANSI standards applicable in both the United States and Canada.
The front turn signal of the Volvo 245 shifted away from the 1156 in 1987, when the specification changed to the 1157NA, followed by the 1034NA in 1988-1989.
Both the 1157NA and the 1034NA are dual-filament bulbs rated at 12V with a 21W/5W output, and both use a BAY15d bayonet base with natural amber glass.
The BAY15d base used by the 1157NA and 1034NA differs from the BA15s base used by the 1156. These two base types are not interchangeable, as the BAY15d features offset locating pins to accommodate dual-filament wiring, while the BA15s has a single pin arrangement suited to single-filament operation.
The 1034NA is described as a variant of the 1157NA. Both share the same base type, voltage, and wattage ratings, with the natural amber glass coating being a defining characteristic of both types.
Because the rear turn signal retains the 1156 specification throughout 1975-1989 while the front specification changes across the same period, the front and rear positions require different bulb types for model years 1987-1989.
