Honda Motorcycle CBR600F Hurricane Turn Signal Bulb Size
Honda Motorcycle CBR600F Hurricane front turn signal uses a 1157 bulb size, while rear turn signal requires either P21W or 1073 bulb size. The replacement chart covers 1987 to 1989 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 CBR600F Hurricane uses three distinct bulb types across its front and rear turn signal positions for the 1987-1989 model years: the 1157, P21W, and 1073.
The 1157 is an ANSI-standard dual-filament bulb rated at 12V with a 21W main filament and a 5W secondary filament, fitted with a BAY15d bayonet base. Its dual-filament design distinguishes it from the single-filament types used elsewhere on the same motorcycle.
The 1157 bulb serves as the front turn signal across all three model years, 1987-1989, making it the most consistently specified bulb in these turn signal applications.
The BAY15d base of the 1157 is offset-pin, meaning the two pins are positioned at different heights around the base. This prevents accidental installation of a single-filament bulb in a socket designed for dual-filament operation.
The P21W is an ECE-standard single-filament bulb rated at 12V, 21W, with a BA15s bayonet base. It is the rear turn signal bulb for the 1988-1989 model years.
The 1073 is an ANSI-standard single-filament bulb rated at 12V, 13W, also with a BA15s bayonet base, and is specified as the rear turn signal bulb for the 1987 CBR600F Hurricane only.
Although the P21W and 1073 share the same BA15s base type, their wattage ratings differ significantly, at 21W and 13W respectively. Substituting one for the other may affect turn signal flash rate, as most flasher relays are load-sensitive.
The 1073 is described as a lower wattage variant of the 1156. The 1156 and 1073 share the BA15s base but are not rated identically, so they are not direct substitutes without accounting for the wattage difference.
The P21W follows ECE regulations, which are used in Europe and internationally, while the 1157 and 1073 follow ANSI standards used in the US and Canada. The presence of both standards within the same vehicle's specification reflects regional variation in component sourcing or market configuration.
Because the front sockets are wired for the dual-filament 1157 with its BAY15d base, and the rear sockets use the single-filament BA15s base, the front and rear turn signal bulbs on the CBR600F Hurricane are not interchangeable with one another.
