Giant C116 motorcycles utilize an H5001 bulb size for high beam headlight operation and an H5006 bulb size for low beam headlight operation. The replacement chart covers 1984 through 1989 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 Giant C116 uses the H5001 bulb type for high beam headlights across all 1984-1989 model years. The H5001 is an ANSI-standard sealed beam unit recognized in both the United States and Canada, operating at 12 volts.
The H5001 is a 4-inch square sealed beam unit. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
The Giant C116 uses the H5006 bulb type for low beam headlights across all 1984-1989 model years. Like the H5001, it is an ANSI-standard unit recognized in the United States and Canada, operating at 12 volts.
The H5006 is a 5.75-inch round sealed beam unit. It also follows the sealed beam construction, meaning the whole unit is replaced upon failure rather than a separate bulb component.
The H5001 and H5006 are not interchangeable with each other. The high beam and low beam positions on the Giant C116 use physically distinct sealed beam units that differ in both shape and size.
