Triumph Tiger high beam headlight bulbs measure H9 or 9003 in size, while low beam headlight bulbs measure H7 or 9003 in size. The replacement chart covers vehicle production spanning 1996 to 2011 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 H9 bulb is an ECE-standard single-filament halogen type rated at 12V and 65W, fitted with a PGJ19-5 base. It serves as the high beam headlight bulb on the Triumph Tiger for model years 2007-2011.
The 9003 bulb follows the ANSI standard used in the US and Canada. Unlike the H9 and H7, it carries two filaments within a single housing, rated at 12V with a 60W high beam filament and a 55W low beam filament, and uses a P43t base.
Because the 9003 is a dual-filament bulb, it handles both high and low beam functions from a single unit. On the Tiger for model years 1996-2006, the same 9003 bulb position covers both the high beam and low beam headlight circuits.
Starting with the 2007 model year, the Tiger moved to a split-bulb headlight system, where the high beam and low beam positions each require a separate, dedicated single-filament bulb rather than one shared dual-filament unit.
The H7 bulb is an ECE-standard single-filament halogen type rated at 12V and 55W, using a PX26d base. It is approved for use in the US and Japan in addition to European and worldwide markets, and it fills the low beam position on the Tiger for model years 2007-2011.
The H9 and H7 bulbs share the same voltage and ECE approval status but differ in wattage, filament base type, and headlight position. Substituting one for the other is not supported by these specifications, as each occupies a distinct socket with a different base design.
The PGJ19-5 base of the H9 and the PX26d base of the H7 are physically incompatible with each other and with the P43t base of the 9003, meaning no cross-fitting between these three bulb types is possible without modification.
The 9003 bulb, while an ANSI-designated type, is electrically and physically equivalent to the ECE H4 bulb, which shares the same P43t base and dual-filament configuration, making the two interchangeable in practice across markets.
