BMW Motorcycle HP2 Megamoto uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2007 to 2009 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb type is the sole bulb size specified across all headlight positions for the BMW Motorcycle HP2 Megamoto, covering both high beam and low beam functions for the 2007-2009 model years.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
The 9003 operates on a 12-volt electrical system, which is standard for motorcycle applications of this type.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange that physically locks the bulb into the housing and ensures correct alignment of the filaments relative to the reflector.
The 9003 is defined under ANSI standards and is the designation used in the United States and Canada. It is functionally equivalent to the H4 bulb used under European and international standards, though the designations originate from different standardization bodies.
Because the BMW Motorcycle HP2 Megamoto uses a single 9003 bulb to serve both high and low beam functions, replacing the headlight bulb affects both beam modes simultaneously.
The P43t base is not interchangeable with other common base types such as P14.5s or PX26d, and substituting a bulb with a different base would result in an incompatible fit within the headlight housing.
