The Triumph Daytona 900 headlight bulb uses a 9003 size for both high and low beam applications. The replacement chart covers vehicle production years from 1994 to 1996 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 type specified across all headlight positions for the Triumph Daytona 900, covering model years 1994-1996 for both high beam and low beam functions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam output and one at 55W for low beam output.
Operating voltage for the 9003 is 12V, consistent with standard 12-volt motorcycle electrical systems.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount that physically orients the filaments in a fixed position relative to the reflector housing.
The 9003 designation follows ANSI standards applicable in the United States and Canada. Its international equivalent is the H4, which shares the same construction and P43t base but is classified under a different naming convention.
Because the Triumph Daytona 900 uses a single 9003 bulb type to serve both high and low beam functions in each headlight position, the two circuits draw from the same physical bulb rather than separate units.
