Additional Notes

The 1157 is the sole tail light bulb type listed for the Polaris 800 SwitchBack across all specified model years.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically stop and tail light operation.
It operates on a 12-volt electrical system and draws 21 watts on the high-filament circuit and 5 watts on the low-filament circuit.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation by ensuring only one rotational orientation fits the socket.
The 1157 conforms to ANSI standards and is recognized across both the United States and Canada, reflecting a widely standardized automotive bulb format.
The Polaris 800 SwitchBack (2004-2005 and 2009-2011) shares the same 1157 tail light bulb specification, indicating socket and electrical compatibility across those listed years.
Because the 1157 is a dual-filament type, substituting it with a single-filament equivalent such as the 1156 would result in the loss of one lighting function and is not a compatible replacement.
