The Triumph Tiger Explorer high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 2012 to 2016.
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 on the Triumph Tiger Explorer, covering model years 2012-2016.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
Because the 9003 carries both filaments within one housing, the Triumph Tiger Explorer uses the same bulb part number for both the high beam and low beam headlight positions.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style fitting with a 43mm collar width.
The 9003 designation is an ANSI standard recognized in the United States and Canada. It is electrically and mechanically equivalent to the H4 bulb used under international IEC standards, though the designations originate from different standardization bodies.
The H4 and 9003 share the same P43t base and identical wattage ratings, making them physically interchangeable in most applications. Fitment should be confirmed against the specific socket and housing before substitution.
