The Indian Springfield headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers vehicle production years from 2016 to 2018 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole bulb type listed across all headlight positions for the Indian Springfield, covering model years 2016-2018.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
Because the 9003 serves both the high beam and low beam positions on the Indian Springfield (2016-2018), a single bulb type handles the full headlight function rather than requiring separate bulbs for each mode.
The 9003 operates on a 12V electrical system, which is standard for motorcycle applications of this type.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange width, which physically determines socket compatibility and is not interchangeable with other base types.
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 bulb is sometimes cross-referenced with the H4 bulb, though the two are not fully interchangeable due to differences in beam pattern certification between North American and European standards.
