The Oldsmobile Super 88 front and rear turn signal bulb sizes include 1157, 1034, and 1154 configurations across different model variations. The replacement chart covers 1951 through 1964 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 1034 bulb is the most frequently specified turn signal bulb across the Oldsmobile Super 88 lineup, appearing in both front and rear positions for the 1953-1963 model years.
All three bulb types used in the Super 88 turn signal system, the 1157, 1034, and 1154, share the BAY15d bayonet base, a dual-pin offset base design that physically locks the bulb into the socket with a twist.
All three bulb types are dual-filament units, meaning a single bulb serves two lighting functions simultaneously, typically combining a brighter filament for the turn signal flash with a dimmer filament for a steady running or parking light.
The 1034 and 1157 are both rated at 12V and share a 21W/5W filament output, with the 1034 classified as a variant of the 1157 under the ANSI standard.
Despite their close relationship, the 1034 and 1157 are not confirmed as interchangeable in these specifications, and the 1964 Super 88 is specifically listed with the 1157 rather than the 1034 used in the preceding model years.
The 1154 bulb, fitted to the 1951-1952 Super 88 in both front and rear positions, is rated for 6V or 12V operation, reflecting the automotive industry's transition from 6-volt to 12-volt electrical systems during that era.
The 1154 is described as an older variant of the 1157 and shares the same BAY15d base, though its dual-voltage rating distinguishes it technically from the strictly 12V 1034 and 1157 types.
All bulb designations in these specifications follow the ANSI standard applicable to the United States and Canada, indicating standardized physical and electrical characteristics within that regional framework.
