The Triumph Tiger 800 high beam and low beam headlight both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2011 to 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Triumph Tiger 800 uses the 9003 bulb size for both high beam and low beam headlights across all listed model years from 2011-2018.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions simultaneously.
The 9003 bulb operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange width, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it the North American classification for this bulb type.
The 9003 and H4 bulbs share the same dual-filament design and P43t base, though they originate from different regional standards, and substitution between them warrants verification of exact electrical and physical compatibility before use.
