The Polaris Slingshot S headlight bulb uses H9 and H3 sizes for both high beam and low beam applications. Replacement chart data covers 2018 to 2019 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 2018-2019 Polaris Slingshot S uses two distinct bulb types across its headlight assembly: the H9 for the center position and the H3 for the outer position, with this dual-bulb arrangement applying 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 used in Europe and worldwide, and carries approval for use in the United States as well. It uses a PGJ19-5 base.
The H3 is a single-filament halogen bulb operating at 12V and 55W, also built to the ECE standard. It uses a PK22s base and holds approval in the United States and Japan in addition to ECE-regulated markets.
Because the H9 and H3 use different base types, PGJ19-5 and PK22s respectively, the two bulbs are not interchangeable with each other despite both being single-filament halogen types operating on a 12V system.
The center headlight position in the Slingshot S draws more wattage than the outer position, with the H9 rated at 65W compared to the H3 at 55W, a distinction relevant when calculating electrical load or selecting equivalent replacement bulbs.
The identical bulb configuration across both the high beam and low beam sub-parts indicates that the center and outer positions each serve dual roles within the headlight system rather than being dedicated to a single beam function.
