The Indian Chief Classic headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers vehicle production spanning 2010 to 2018 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Indian Chief Classic uses the 9003 bulb size for both high beam and low beam headlight positions across the 2010-2018 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains separate filaments for both the high beam and low beam functions.
The 9003 operates at 12 volts and carries a wattage rating of 60W on the high beam filament and 55W 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 housing.
The 9003 is an ANSI-standardized bulb recognized in the United States and Canada, and it is electrically and physically equivalent to the European H4 bulb type.
Because the 9003 serves both beam functions in the Indian Chief Classic, a single bulb replacement addresses the entire headlight output for that housing.
The H4 designation is the international equivalent of the 9003, and bulbs sold under either designation share the same filament configuration, voltage, wattage, and base type, making them interchangeable in this application.
