Honda Motorcycle CB1100 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2013 to 2014 production 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 9003 is the sole bulb type listed across all headlight positions for the Honda Motorcycle CB1100, covering both the high beam and low beam functions for 2013-2014.
The 9003 is an ANSI-standard bulb recognized in the United States and Canada, distinguishing it from the internationally designated H4 bulb, which shares the same physical and electrical characteristics but carries a different designation under ECE standards.
As a dual-filament halogen bulb, the 9003 houses two separate tungsten filaments within a single glass envelope, with one filament dedicated to the high beam function and the other to the low beam function.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The P43t base is the mounting interface of the 9003 bulb, a bayonet-style base with a 43mm collar that positions and locks the bulb within the headlight housing.
Because the 9003 serves both the high beam and low beam headlight positions on the CB1100, a single bulb type fulfills both lighting functions rather than requiring separate bulbs for each.
