The BMW Motorcycle F800ST uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 2006 to 2012 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 BMW Motorcycle F800ST uses the H7 bulb type for both high beam and low beam headlights across all listed model years, 2006-2012.
The H7 is a single-filament halogen bulb, meaning each unit serves only one lighting function. As a result, the F800ST requires separate H7 bulbs for the high beam and low beam positions rather than a single dual-filament unit.
The H7 bulb operates at 12 volts and 55 watts, which are standard ratings for halogen headlight applications in motorcycles and passenger vehicles.
The H7 bulb uses a PX26d base, a two-pin connector with a specific locking collar. Bulbs with different base types are not physically interchangeable with this fitting, regardless of similar wattage or voltage ratings.
The H7 is built to ECE (Economic Commission for Europe) standards, which govern light output, beam pattern, and construction quality for road use across Europe and many other markets worldwide.
The H7 specification also carries approval for use in the United States and Japan, making it a globally accepted bulb type across major automotive regulatory frameworks.
Because both the high beam and low beam positions on the BMW Motorcycle F800ST share the same H7 specification throughout 2006-2012, a single bulb type covers both replacement needs for the entire production run listed.
