14. Headlights. It's either off or on. Sidelights are pathetic. Nobody sees them, so why do some people insist on riding with just sidelights? Are you saving your headlight bulbs? Do you only want other road users to 'maybe' see you? I know most modern bikes have dipped headlights on permanently, but the old bikes are still switchable. Incidentally, there is the odd occasion where you are more visible without them on. If the sun is going down behind you, by switching off, you become silhouetted aginst the sun. Whereas, with your lights on, you become part of the glare.
