Andy. You say the lighting on the side of the saddlebags are not factory installed? I'm a little confused here. All 'Wings I've come across, including the one I previously owned, have these lights??
Saddlebag and trunk lights were not installed on 1988 - 2000 Gold Wing's at the assembly plant.
Honda did have saddlebag lights (see attached) that could be installed by owners.
There were a couple aftermarket companies that made saddlebag and trunk lights that could be installed by owners.
