I can see the purpose of a light on the back of bracket cars and such where they run at night and rather quickly and no chutes. But when running blown cars (or fast) that require chutes (obscures the tail light) the track is supposed to have the proper safety crew on top to relay that the track is clear or there is a problem. Never was asked to have a light 7.60 and faster.But I do carry in the toolbox a clip-on bicycle(battery powered) just in case.
