Honda Motorcycle CBR600RR headlight bulbs utilize H7 size for both high beam and low beam functions. The replacement chart covers 2003 to 2020 model 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 Honda Motorcycle CBR600RR uses the H7 bulb type for both its high beam and low beam headlights across all model years from 2003-2020.
The H7 is a single-filament halogen bulb, meaning each headlight function on the CBR600RR requires a separate, dedicated bulb rather than a shared dual-filament unit.
H7 bulbs operate on a 12V electrical system and draw 55 watts, which are standard ratings for halogen headlight applications in motorcycles and other vehicles.
The H7 bulb uses a PX26d base, a two-pin connector with a specific locking collar that is not interchangeable with other common halogen bases such as H4 or H11.
The H7 is an ECE-rated bulb, a standard recognized across Europe and much of the world, and it also carries approval for use in the United States and Japan.
Because both the high beam and low beam positions on the CBR600RR share the same H7 specification, a single bulb type serves both functions, though each position requires its own individual unit.
The PX26d base features a retaining spring or clip mechanism for mounting, and substituting a bulb with a physically different base type would not fit the CBR600RR's headlight housing without modification.
The consistent H7 fitment across the entire 2003-2020 production span of the CBR600RR indicates that replacement bulbs sourced for any year within that range are cross-compatible with all other years in the same range.
