Additional Notes

The Polaris Lite GT uses two distinct brake bulb types across its production run: the 1034 for model years 1993-1997 and the 90 for model years 1991-1992.
The 1034 is an ANSI-standard dual-filament bulb rated at 12V and 21/5W, meaning it operates two separate filaments at different wattages within a single housing, a design commonly used to serve both brake and tail light functions simultaneously.
The 1034 uses a BAY15d bayonet base, which is an offset-pin base that physically prevents incorrect single-filament bulbs from being seated in its socket.
The 1034 is a variant of the widely available 1157 bulb type, placing it within a well-established family of dual-filament automotive bulbs.
The 90 is an ANSI-standard single-filament bulb rated at 12V and 13W, operating only one filament and therefore serving a single lighting function.
The 90 uses a BA15s bayonet base, which features symmetrically placed pins, distinguishing it from the offset BAY15d base of the 1034.
The base types of the 1034 and the 90 are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both using 12V bayonet-style bases.
