Buick Super front turn signal bulbs utilize 1034 or 1154 size specifications, while rear turn signal bulbs use 1034, 1073, or 1129 size options. The replacement chart covers 1950 through 1958 vehicle production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1034 bulb is the most frequently specified type across the Buick Super turn signal fitments, appearing in both the front and rear positions for the 1958 model year, and in the front position alone for 1954-1957.
The 1034 is a dual-filament bulb rated at 12V and 21/5W, mounted on a BAY15d bayonet base, and is classified as a variant of the widely referenced 1157 under ANSI standards applicable in the US and Canada.
The 1154 bulb serves as the front turn signal for the Buick Super across the 1950-1953 model years. It is also a dual-filament type with a BAY15d bayonet base and is described as an older variant of the 1157, rated for operation at either 6V or 12V.
The dual-voltage rating of the 1154 reflects its origin in an era when automotive electrical systems were transitioning between 6-volt and 12-volt standards, making it compatible with both configurations.
The 1073 bulb is specified for the rear turn signal position across the 1954-1957 model years. Unlike the other bulbs in these specifications, it is a single-filament type, mounted on a BA15s bayonet base and rated at 12V, 13W.
The BA15s base of the 1073 is not interchangeable with the BAY15d base used by the 1034, 1154, and 1129 bulbs. The BAY15d base features offset pins to prevent incorrect installation of dual-filament bulbs, while the BA15s base uses symmetrical pins suited to single-filament applications.
The 1129 bulb is specified for the rear turn signal position on the Buick Super for 1950-1953. It shares the BAY15d bayonet base and 12V, 21/5W rating with the 1034, and is also classified as a variant of the 1157.
Although the 1034 and 1129 share the same base type, voltage, and wattage rating, they are listed as distinct ANSI bulb numbers and are not confirmed as interchangeable within these specifications.
The rear turn signal of the 1958 Buick Super uses the 1034 bulb, which differs from the 1073 specified for the same position in 1954-1957, representing a change from a single-filament to a dual-filament rear turn signal configuration.
All four bulb types in these specifications conform to ANSI standards recognized in both the US and Canada, indicating standardized physical and electrical characteristics within those markets.
