Kawasaki KLR650 Headlight Bulb Size

The Kawasaki KLR650 headlight bulb utilizes H7 and 9003 size specifications for both high and low beam functions. The replacement chart covers 1987 through 2018 production years with corresponding bulb size data.

Additional Notes

The two bulb types specified for the Kawasaki KLR650 headlight positions are the H7 and the 9003, both halogen bulbs operating on a 12-volt electrical system.
The H7 is a single-filament halogen bulb rated at 55 watts, fitted with a PX26d base, and governed by the ECE standard used across Europe and much of the world, though it also carries approval in the United States and Japan.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 60 watts on the high beam filament and 55 watts on the low beam filament, and follows the ANSI standard used in the United States and Canada.
Because the H7 carries a single filament and the 9003 carries two filaments, the two types use physically different base configurations and are not interchangeable with one another.
The Kawasaki KLR650 used the 9003 bulb in both the high beam and low beam headlight positions for model years 1987-2007.
Starting with the 2008 model year, the KLR650 transitioned to the H7 bulb for both the high beam and low beam headlight positions, a fitment that continued through the 2018 model year.
The shift from a dual-filament 9003 to a single-filament H7 across both headlight positions indicates that the 2008 redesign moved to a projector or reflector housing with separate dedicated bulbs for each beam function rather than a single bulb handling both.
When sourcing a replacement, the correct bulb type is determined strictly by model year, as a 9003 bulb physically cannot seat into an H7 housing due to the differing base designs.
