Polaris 600 SwitchBack Brake Bulb Size

Additional Notes

• The Polaris 600 SwitchBack uses the 1157 bulb type across all listed model years, spanning 2004-2011.
• The 1157 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared across manufacturers.
• The 1157 is a dual-filament bulb, which allows it to serve two distinct brightness levels within a single housing, a characteristic common in brake and tail light applications where separate stop and running light functions are required.
• The bulb operates on a 12-volt system and carries a wattage rating of 21W for the high-intensity filament and 5W for the low-intensity filament.
• The 1157 uses a BAY15d bayonet base, a two-pin offset base design that physically prevents incorrect insertion by positioning the two pins at different heights along the base.
• The BAY15d base is a widely used standard, meaning 1157 bulbs are broadly available as direct replacements across automotive and powersports supply channels.
• Because the 1157 is a dual-filament type, substituting it with a single-filament equivalent such as the 1156, which shares a similar bayonet base, would result in the loss of one functional circuit and is not a compatible replacement.
