Honda Motorcycle CBR125R uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2004 to 2011 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 CBR125R uses the H7 bulb type for both the high beam and low beam headlight positions across the 2004-2011 model years, with the exception that 2010 is not represented in the specifications.
The H7 is a single-filament halogen bulb, meaning each headlight position requires a dedicated bulb rather than a shared dual-filament unit.
H7 bulbs operate on a 12V, 55W electrical rating, which reflects the standard power draw expected from the motorcycle's electrical system for each headlight circuit.
The H7 bulb uses a PX26d base, a two-pin connector with a plastic collar that locks into the housing. Bulbs with different base types are not interchangeable with this fitting even if the wattage matches.
The H7 is produced to ECE standards, a regulatory framework covering Europe and many other markets worldwide, and it also carries approval for use in the United States and Japan.
Because both the high beam and low beam positions share the same H7 specification across all listed years, a single bulb type serves the entire headlight assembly on the CBR125R.
