Polaris 600 IQ Widetrack Brake Bulb Size

Additional Notes

• The Polaris 600 IQ Widetrack uses the 3157 bulb for its brake light across the 2010-2017 model years.
• The 3157 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared by all compliant manufacturers.
• The 3157 is a dual-filament bulb, which allows it to serve two distinct brightness levels within a single housing. In brake light applications, the higher-output filament activates under braking while the lower-output filament typically handles a secondary function such as running lights.
• The bulb operates on a 12-volt circuit and draws 27 watts on its high-intensity filament and 7 watts on its low-intensity filament.
• The T25 designation refers to the bulb's wedge-base form factor, a bayonet-style base with two offset contact pins that prevent incorrect insertion orientation.
• The dual-pin configuration of the 3157 is a fitment-critical detail. Single-filament bulbs sharing a similar base profile, such as the 3156, are not interchangeable with the 3157 in dual-function sockets without loss of one lighting function.
