Honda Motorcycle VT600C Shadow VLX headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 1988 to 2007 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 VT600C Shadow VLX uses the 9003 bulb size for both the high beam and low beam headlight positions across all model years from 1988-2007.
The 9003 is an ANSI-standard halogen bulb recognized in the United States and Canada, operating on a 12-volt electrical system with a dual-filament design rated at 60 watts for high beam and 55 watts for low beam.
The dual-filament construction of the 9003 allows a single bulb to serve both the high beam and low beam functions, which is why the same part number appears in both headlight positions on this motorcycle.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm collar, which physically determines fitment and is not interchangeable with single-filament bases such as those found on 9005 or 9006 bulbs.
The 9003 is electrically and physically equivalent to the European H4 bulb, meaning H4-designated bulbs with a P43t base are generally cross-compatible with the 9003 specification.
Because the same bulb type is specified across all 20 model years covered, a single 9003 bulb serves the full production run of the VT600C Shadow VLX without variation by year.
