The Pontiac Super Chief front and rear turn signal bulbs both utilize a 1034 size bulb for proper operation. The replacement chart covers vehicle production spanning 1957 to 1958.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Pontiac Super Chief uses the 1034 bulb across all listed positions and model years, making it the sole bulb type present in these turn signal specifications.
The 1034 is an ANSI-standard bulb recognized in both the United States and Canada, operating at 12 volts with a dual-filament design rated at 21/5 watts.
The dual-filament construction of the 1034 allows it to serve two distinct brightness levels within a single bulb, which is typical for applications requiring both a running light function and a brighter turn signal flash.
The 1034 uses a BAY15d bayonet base, a two-pin offset base type where the two pins are positioned at different heights to ensure correct orientation during installation.
The 1034 is described as a variant of the 1157, a bulb that shares the same BAY15d base and dual-filament design but operates at slightly different wattage ratings, meaning the two types are related but not identical in output.
The Pontiac Super Chief carries the 1034 specification for both the front and rear turn signal positions across the 1957-1958 model years, indicating a consistent bulb requirement throughout the listed production period.
