The Triumph Daytona 900 Super III uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1994 to 1997 production years 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 9003 bulb is the sole bulb type specified across all headlight positions for the Triumph Daytona 900 Super III, covering both high beam and low beam functions for the 1994-1997 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60 watts for high beam output and one rated at 55 watts for low beam output.
Because both the high beam and low beam positions share the same 9003 specification, a single bulb type serves both lighting functions rather than requiring separate bulbs for each.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar used to seat and lock the bulb into its housing.
The 9003 designation follows the ANSI standard recognized in the United States and Canada. It is physically and electrically equivalent to the international HB2 designation, and both refer to the same bulb construction.
The P43t base is not universal across halogen bulb types. Bulbs with differing base configurations are not interchangeable with the 9003, even when voltage ratings are similar.
