Honda Motorcycle GL1800 Gold Wing uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2001 through 2017 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 GL1800 Gold Wing uses the H7 bulb type for both its high beam and low beam headlights across the 2001-2017 model years, with no variation between positions or years in the specifications.
The H7 is a single-filament halogen bulb, meaning each headlight position on the GL1800 Gold Wing requires a dedicated bulb rather than a dual-filament unit serving both functions from a single housing.
H7 bulbs use a PX26d base, a two-pin connector with a specific keyed orientation that prevents incorrect installation and is not interchangeable with other common bases such as the H4's P43t or the H11's PGJ19-2.
The H7 operates at 12 volts and 55 watts, which are standard ratings for halogen headlight bulbs in this class and reflect the electrical load each bulb places on the motorcycle's charging system.
The H7 is an ECE-rated bulb, a standard governed by the United Nations Economic Commission for Europe and recognized across European and many worldwide markets, with additional approval in the United States and Japan.
Because both the high beam and low beam positions on the GL1800 Gold Wing share the same H7 specification, a single bulb type covers both replacements, though the two positions remain physically separate installations.
The consistent use of the H7 across all listed model years means that bulbs sourced for any year within the 2001-2017 range are specification-compatible with any other year in that same range for the GL1800 Gold Wing.
Substituting a bulb with a different base type, such as an H1 or H3, would be physically incompatible with the PX26d socket used in the GL1800 Gold Wing's headlight housings.
