The BMW Motorcycle HP2 Sport uses H7 bulbs for both high beam and low beam headlight functions, with identical size specifications across both lighting positions. The replacement chart covers 2008 to 2010 model years and details bulb size requirements for headlight applications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base. The single-filament design means one bulb serves one lighting function, which is why the BMW Motorcycle HP2 Sport uses separate H7 units for the high beam and low beam circuits rather than a dual-filament alternative.
The H7 bulb conforms to ECE standards, the regulatory framework governing lighting equipment across Europe and much of the world. It also carries approval in the United States and Japan, giving it broad international acceptance across major automotive markets.
The PX26d base is a keyed, single-pin connector specific to H7 bulbs. The keying prevents incorrect installation by ensuring the bulb can only be seated in one orientation, which is relevant to maintaining proper beam alignment in a headlight housing.
Both the high beam and low beam headlight positions on the HP2 Sport use the H7 specification across the 2008-2010 model years. Because both positions share the same bulb type, the same replacement unit is physically compatible with either socket on the motorcycle.
Although the high beam and low beam sockets accept the same H7 bulb, the two circuits remain electrically independent. Substituting a bulb between positions does not alter the wattage or voltage draw, as both operate at 12V and 55W.
