The Triumph Daytona 1200 headlight bulb uses a 9003 size for both high and low beam functions. The replacement chart covers 1993 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 Triumph Daytona 1200 uses the 9003 bulb for both high beam and low beam headlight positions across the 1993-1997 model years.
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 rated at 55W for low beam output.
The 9003 bulb operates on a 12-volt 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 that locks the bulb into the headlight housing through a twist-and-seat action.
The 9003 designation is an ANSI standard recognized in the United States and Canada. It is functionally equivalent to the H4 bulb used under international IEC standards, though the designations originate from different standardization bodies.
Because the same 9003 bulb serves both the high beam and low beam positions, the Daytona 1200 headlight assembly relies on a single-bulb, dual-filament design rather than separate bulbs for each function.
The shared 9003 specification across all listed model years means that a single bulb type covers the full 1993-1997 production range without variation between years or beam positions.
