The Polaris Slingshot headlight bulb uses H9 and H3 sizes for both high beam and low beam applications. Replacement specifications are documented in a chart covering 2015 through 2019 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Polaris Slingshot uses two distinct bulb types across its headlight system for model years 2015-2019: the H9 in the center position and the H3 in the outer position, a split arrangement that applies equally to both high beam and low beam functions.
The H9 is a single-filament halogen bulb operating at 12V and 65W, built to the ECE standard with a PGJ19-5 base. It holds approval for use in the United States in addition to European and worldwide markets.
The H3 is a single-filament halogen bulb operating at 12V and 55W, also built to the ECE standard, with a PK22s base. Its approval extends to the United States and Japan alongside European and worldwide markets.
The PGJ19-5 base of the H9 and the PK22s base of the H3 are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both being single-filament halogen designs running on 12V systems.
The H9 draws 65W while the H3 draws 55W, a 10W difference that reflects distinct electrical load requirements for each socket position in the Slingshot headlight assembly.
The center and outer position designations indicate that the Slingshot headlight housing contains multiple bulb sockets, with each position requiring its specific bulb type regardless of whether the high beam or low beam circuit is being serviced.
The bulb specifications for both the high beam and low beam headlights are identical across all model years 2015-2019, with no variation in bulb type by year or beam function.
