The Indian Scout high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2015 to 2021.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Indian Scout uses the 9003 bulb type for both high beam and low beam headlight positions across the 2015-2021 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar, and this base type determines physical fitment into the headlight socket.
The 9003 carries an ANSI designation, indicating it conforms to a standardized specification recognized in the United States and Canada, which governs its electrical and physical characteristics.
The 9003 and H4 bulb types share the same dual-filament design and P43t base, making them functionally interchangeable in many applications, though the 9003 designation reflects the North American ANSI standard while H4 reflects the European ECE standard.
