The BMW Motorcycle F800S uses H7 bulbs for both high beam and low beam headlight applications, with the size remaining consistent across both functions. The replacement chart covers 2006 to 2008 model production years and documents bulb size specifications for this motorcycle.
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 each H7 unit serves only one lighting function, which is why the BMW Motorcycle F800S uses separate H7 bulbs for the high beam and low beam circuits rather than a single dual-filament unit.
The PX26d base is a keyed, three-tab bayonet-style connector. The keying prevents incorrect orientation during installation, as the single filament must be positioned precisely within the reflector housing to produce the correct beam pattern.
The H7 carries ECE certification, the regulatory standard applied across Europe and numerous other markets worldwide. It also holds approval in the United States and Japan, giving it broad international regulatory acceptance.
At 55 watts, the H7 falls within the standard halogen output range for motorcycle headlighting. Both the high beam and low beam positions on the F800S share this same wattage rating.
The F800S uses the H7 bulb type across both lighting positions and across all three model years covered by the specifications, spanning 2006-2008. No variation in bulb type occurs between those years or between the two beam functions.
Because the high beam and low beam housings both accept the H7, the bulb is physically interchangeable between the two positions. However, the beam optics of each housing are calibrated for a specific function, so the housing itself determines the output pattern rather than the bulb.
