What is the point of sidelights? I only ever use sidelights when approaching the camp gates at night to avoid blinding the guard (an act becoming rarer these days it seems). I ask because I am getting increasingly annoyed by drivers driving around in poor light or full dark on sidelights. In fast flowing traffic you often can't see them in your mirrors because their tiny little dim lights are outshone by the car or truck behind or to the side of them. Is there a good reason to use sidelights when mobile, or are they out of date and should be scrapped? personally I drive in all weather conditions with dipped headlights and would be happy if my car automatically turned them on as the engine started. Talking of lights - why do drivers not use lights in heavy rain or snowfall? 'Oh, I can see fine'. Good for you, but no-one else can see you!
