Additional Notes

The 3157 is the brake bulb size specified for the Polaris Sportsman 1000 XP across the 2015-2017 model years.
The 3157 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in both the United States and Canada.
As a dual-filament bulb, the 3157 operates two separate tungsten filaments within a single envelope, one rated at 27W for the brake/stop function and one at 7W for the running light function.
The T25 designation refers to the bulb's tubular glass envelope, with the numeric portion indicating a width of 25 eighths of an inch, a sizing convention common in ANSI bulb nomenclature.
The 3157 operates on a 12V electrical system, consistent with the standard automotive and powersports vehicle voltage.
The dual-filament design of the 3157 means it is not directly interchangeable with single-filament bulbs of similar physical form, as substituting a single-filament type would disable one of the two lighting functions.
