Additional Notes

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 brightness levels within a single bulb, a configuration typical of combined stop and tail light applications.
The 1034 uses a BAY15d bayonet base, which is an offset twin-pin mount designed to allow installation in only one rotational orientation, preventing incorrect fitment.
The 1034 is a variant of the more widely known 1157 bulb. These two types share a similar form and function but are not directly interchangeable due to differences in their electrical ratings.
The Polaris Longtrak uses the 1034 bulb across its 1985-1989 model years for the brake light position.
