BMW Motorcycle K1200S headlight bulbs utilize H7 size for both high and low beam functions. The replacement chart covers 2005 to 2008 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 H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base. The PX26d base uses a two-pin configuration with a plastic collar, which locks into compatible housings at a fixed rotational position.
The H7 bulb carries ECE certification, meaning it meets the regulatory lighting standards used across Europe and in numerous countries worldwide. It also holds approval in the United States and Japan, giving it broad international acceptance.
The BMW Motorcycle K1200S uses the H7 bulb size for both the high beam and low beam headlight positions across the 2005-2008 model years.
Because the high beam and low beam positions share the same H7 specification on the K1200S, the two housings each require a dedicated bulb rather than a single dual-filament unit serving both functions.
The single-filament construction of the H7 means the entire bulb must be replaced when the filament fails, as no secondary filament is present to maintain any level of output.
The PX26d base is not interchangeable with other common halogen bases such as the H1, H4, or H11. Substituting a bulb with a different base type is not compatible with H7 housings.
