The BMW Motorcycle HP4 uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2013 to 2014 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 H7 is the bulb type specified for both the high beam and low beam headlight positions on the BMW Motorcycle HP4 across the 2013-2014 model years.
The H7 is a single-filament halogen bulb, meaning it contains one tungsten filament and relies on a halogen gas cycle to extend filament life and maintain lumen output over time.
The H7 operates at 12 volts and 55 watts, which places it in the standard low-voltage automotive halogen range used across a wide variety of road vehicles and motorcycles.
The H7 uses a PX26d base, a two-pin bayonet-style connector that is not interchangeable with other common halogen bases such as the H4's P43t or the H11's PGJ19-2.
The H7 carries ECE certification, making it compliant with European and international lighting regulations, and it also holds approval for use in the United States and Japan.
Because the same H7 bulb type is specified for both the high beam and low beam positions on the BMW Motorcycle HP4, the two headlight housings use separate single-filament bulbs rather than a single dual-filament unit to handle both functions.
