Honda Motorcycle XR650L headlight bulb uses 9003 size for both high and low beam functions. The replacement chart covers 1993 to 2020 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 Honda Motorcycle XR650L uses the 9003 bulb size for both the high beam and low beam headlight positions across the 1993-2020 model years covered in these specifications.
The 9003 is an ANSI-standardized bulb designation used in the United States and Canada, meaning it conforms to a defined set of electrical and physical standards recognized across those markets.
The 9003 is a dual-filament halogen bulb, which means a single bulb contains two separate tungsten filaments housed within one glass envelope, one filament serving the high beam function and the other serving the low beam function.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type is a physical fitment standard, and bulbs with a different base type are not compatible with sockets designed for the P43t.
The 9003 bulb is also commonly cross-referenced with the H4 designation. The H4 is an ECE-standard equivalent sharing the same dual-filament halogen construction, wattage ratings, and P43t base, though the two designations originate from different regional standards bodies.
Because a single 9003 bulb handles both beam functions on the XR650L, replacing the headlight bulb addresses both the high beam and low beam simultaneously rather than requiring separate bulbs for each position.
