The Yamaha XP500 TMAX high beam headlight uses an H7 bulb size while the low beam headlight requires a 9003 bulb size. The replacement chart covers 2009 through 2011 vehicle 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 Yamaha XP500 TMAX uses the H7 bulb for the high beam headlight across the 2009-2011 model years.
The H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base and classified under the ECE standard used in Europe and worldwide, though it also carries approval in the US and Japan.
Because the H7 carries only a single filament, it is dedicated exclusively to one lighting function, which is why the XP500 TMAX uses a separate bulb type for the low beam circuit.
The low beam headlight on the 2009-2011 XP500 TMAX takes the 9003 bulb, an ANSI-standard type used in the US and Canada.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 12V with 60W on the high-filament side and 55W on the low-filament side.
The H7 and 9003 bulbs use physically different bases, PX26d and P43t respectively, making them non-interchangeable with each other despite both being 12V halogen types.
The 9003 bulb's dual-filament design means it is capable of serving both high and low beam functions in a single housing, though in the XP500 TMAX it is assigned only to the low beam position.
The differing wattage values of the 9003 (60W high filament, 55W low filament) reflect the greater light output typically associated with high beam operation compared to low beam output.
