I don't anticipate going out much when it's dark out, but will occaisionally need some running lights at the end of the day. My motor's pull-start, and I'd like to avoid having to carry and maintain a battery. Has anyone tried rigging solar navigation lights? Seems to me that the rear (white) light is not much different than some of the solar garden-path lights you see all over the place for cheap. They're all LED - how hard would it be to rig the charging and battery system for the two red/green lights?
