Polaris 600 RMK Tail Light Bulb Size

Additional Notes

• The 1157 is the tail light bulb type used in the Polaris 600 RMK across the 2000-2011 model years, making it the dominant fitment across this specification range.
• The 1157 is a dual-filament bulb, meaning it serves two lighting functions from a single unit, typically combining a brighter stop light output with a dimmer running light output. It operates at 12V with filament ratings of 21W and 5W.
• The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect insertion by positioning the two pins at different heights along the base.
• The 194 is a miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W, and was the specified tail light fitment for the 1998-1999 model years of the Polaris 600 RMK.
• The 194 is a single-filament wedge-type bulb, which is physically and electrically distinct from the dual-filament 1157 with its bayonet base. The two types are not interchangeable.
• Both the 1157 and 194 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances shared across compliant products from different manufacturers.
• The change in bulb type between the 1999 and 2000 model years represents a shift from the lower-wattage single-filament 194 to the higher-wattage dual-filament 1157, reflecting a difference in tail light assembly design between those model years.
