Additional Notes

The 1034 bulb follows the ANSI standard 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 brightness levels within a single bulb, a characteristic common in parking and stop light applications.
The 1034 uses a BAY15d bayonet base, which is an offset-pin bayonet mount. The offset pin placement prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
The Chevrolet Del Ray uses the 1034 bulb for the parking light position across both the 1957-1958 model years.
The 1034 is a variant of the more widely distributed 1157 bulb. While the two share a similar form factor and BAY15d base, they are not identical, and substitution between them may affect fitment or electrical compatibility.
