The Yamaha RXW10 Attak uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2006 to 2007 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 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high and low beam functions from one housing.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange used to seat and lock the bulb into the headlight housing.
The 9003 designation follows the ANSI standard recognized in the United States and Canada, distinguishing it from the physically identical H4 bulb, which follows ECE standards used in other markets.
The Yamaha RXW10 Attak uses the 9003 bulb for both the high beam and low beam headlight positions across the 2006-2007 model years.
Because the 9003 serves both beam functions in the RXW10 Attak, the high beam and low beam positions share the same bulb type and are therefore interchangeable with one another in terms of part number.
The H4 and 9003 bulbs share the same physical construction and P43t base, though substituting one for the other may carry compliance implications depending on the regulatory market in which the vehicle is operated.
