Additional Notes

The two bulb types specified for the Kawasaki EX250F Ninja 250R headlight system are the 9003 and H7, both halogen bulbs operating on a 12-volt electrical system.
The 9003 is a dual-filament halogen bulb rated at 60W for high beam and 55W for low beam, using a P43t base. Its dual-filament construction means a single bulb unit serves both beam functions within one housing.
The H7 is a single-filament halogen bulb rated at 55W, using a PX26d base. Because it carries only one filament, separate H7 bulbs are required for the high beam and low beam positions.
The 9003 follows the ANSI standard, primarily used in the United States and Canada, while the H7 follows the ECE standard used in Europe and worldwide, with additional approval in the US and Japan.
The P43t base of the 9003 and the PX26d base of the H7 are physically incompatible with each other, meaning the two bulb types are not interchangeable despite both being halogen and operating at 12 volts.
For the Kawasaki EX250F Ninja 250R, the 9003 bulb applies to both the high beam and low beam positions across the 1986-2007 model years.
The H7 bulb applies to both the high beam and low beam positions across the 2008-2012 model years, with each beam position requiring its own individual bulb due to the single-filament design.
The base type change from P43t to PX26d between the 2007 and 2008 model years reflects a headlight housing change, and parts sourced for pre-2008 units are not compatible with 2008-2012 units.
