Honda Motorcycle CB600F 599 uses an H11 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2004 to 2007 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 H11 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PGJ19-2 base. Its single filament means it serves one lighting function per unit rather than combining two functions within the same envelope.
The H11 bulb carries ECE certification, a regulatory standard recognized across Europe and numerous other markets worldwide, and also holds approval for use in the United States.
The Honda Motorcycle CB600F 599 uses the H11 bulb for both the high beam and low beam headlight positions across the 2004-2007 model years covered in the specifications.
Because the high beam and low beam positions share the same H11 bulb type, the two sockets accept the same replacement unit, though each position remains a physically separate installation.
The PGJ19-2 base is a keyed locating base, meaning the bulb seats in a fixed rotational orientation within its housing. Substituting a bulb with a different base type would result in an incompatible fit.
