Additional Notes

The Polaris Tran Sport uses the 1034 bulb for the brake light position across the 1996-1999 model years.
The 1034 is an ANSI-standardized 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 allows a single bulb to serve two lighting functions, with the higher-wattage filament typically handling the brake or turn signal function and the lower-wattage filament handling the running light function.
The 1034 uses a BAY15d bayonet base, which is an offset twin-pin base. The offset pin placement is a deliberate fitment control, as it prevents the bulb from being seated in an incorrect rotational position.
The 1034 is a variant of the 1157 bulb. While both share the BAY15d base and dual-filament design, the 1034 operates at lower wattage than the 1157, which is rated at 21/5W versus the 1157's 26.88/8.26W, making them non-interchangeable despite their physical similarities.
