Well, after investigating a few options, I'm not going to go dual headlights. I am, however, going to use a single oval shaped driving/fog lamp that I will mount under the fork brace. I will wire up it's own circuit with relay and switch and operate it when I need that extra splash of light at night. For circuit, I was considering a power relay that would engage power when the key is turned on, feeding a relay that would turn on when I flip the switch for the lamp. Will the charging system be enough to operate the lamp when I need it?
