Honda Motorcycle GL500 Silver Wing uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1981 to 1982 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the most prominent type in these specifications, serving both the high beam and low beam headlight positions on the Honda Motorcycle GL500 Silver Wing across the 1981-1982 model years.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments within one housing, one rated at 60 watts for high beam output and one at 55 watts for low beam output.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar width.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it a regionally standardized specification rather than a global one.
Because the 9003 handles both high and low beam functions through its dual-filament design, a single bulb type covers all headlight positions on this motorcycle, with no separate bulb required for each beam mode.
The P43t base is not universally interchangeable with other base types, so substituting a bulb with a different base configuration would result in an incompatible fit regardless of voltage or wattage similarity.
