After reviewing the Nevada statutes it seems I need a brake or "stop" light as they call it. Apparently a fairly powerful one at that: NRS 484D.125 Stop lamps " (b) Display a red, amber or yellow light visible from a distance of not less than 300 feet to the rear in normal sunlight" So is there something off the shelf you folks are using? Or am I going to have to build something new? No other lights are required for daytime operation, but 2 mirrors of 7 square inches each are required. Any suggestions? B.
