The Honda Motorcycle CBR954RR headlight bulb size specifications include H7 bulbs for both high beam and low beam functions. The replacement chart covers 2002 to 2003 model years with corresponding bulb size data.
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. Single-filament construction means each bulb serves only one lighting function, which is why the Honda Motorcycle CBR954RR uses separate H7 units for both the high beam and low beam circuits.
The PX26d base is a keyed, twist-lock fitting. Its asymmetric pin arrangement ensures the bulb seats in only one orientation, which is critical for correct filament positioning relative to the reflector.
The H7 carries ECE certification, making it a standard approved for use across Europe and most worldwide markets. It also holds approval in the United States and Japan, giving it broad regulatory acceptance across major automotive markets.
Both the high beam and low beam headlight positions on the CBR954RR use the H7 bulb across the 2002-2003 model years, meaning a single bulb type covers all four headlight sockets on the motorcycle.
Because both beam positions share the same bulb type, an H7 replacement purchased for one position is physically and electrically interchangeable with the other position on this motorcycle.
The 55-watt rating of the H7 is a fixed specification under the ECE standard. Substituting a bulb of a different wattage in the same base format would fall outside the approved specification for this application.
