Additional Notes

The 1034 bulb follows the ANSI standard recognized in 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 lighting functions within a single housing, typically combining stop and tail light operation.
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 a variant of the 1157 bulb. These two types share a similar design but are not interchangeable, as differences in pin spacing or filament ratings can affect fitment and function.
The Chevrolet Del Ray used the 1034 bulb for tail light applications across both the 1957 and 1958 model years.
