Polaris Trail Touring Tail Light Bulb Size

Additional Notes

• The Polaris Trail Touring tail light specifications cover model years 1996-2010 and reference three distinct bulb types: the 3157, 194, and 906.
• The 906 bulb is the most frequently specified type across the Trail Touring lineup, appearing in six consecutive model years from 1996-2002, excluding 2001. It is a miniature wedge bulb in the T10 form factor, rated at 12V and 8W under the ANSI standard used in the US and Canada.
• The 3157 bulb is specified for the 2004-2006 and 2010 model years of the Polaris Trail Touring. It is a dual-filament wedge bulb in the T25 form factor, rated at 12V with a wattage split of 27W for the primary filament and 7W for the secondary filament, also conforming to the ANSI standard.
• The dual-filament design of the 3157 means it is capable of serving two lighting functions, such as combined tail and brake light operation, within a single bulb housing.
• The 194 bulb is specified exclusively for the 2003 model year. It shares the T10 wedge form factor with the 906 but operates at a significantly lower wattage of 3.78W, making the two bulbs electrically distinct despite their physical similarities.
• Because the 906 and 194 bulbs share the T10 wedge form factor, physical fitment alone does not confirm electrical compatibility. The wattage difference between the two types means substituting one for the other without verifying the vehicle's circuit requirements would be inadvisable.
• The 3157 uses the larger T25 wedge base, which is not physically interchangeable with the T10 base shared by the 906 and 194 bulbs.
• All three bulb types in these specifications conform to the ANSI standard and are rated for 12V electrical systems.
