My headlights no longer work on "dim". They work find on "bright". When on "dim", some small light, such as parking lights, come on, but no "dim". All other lights (brake, etc) work, though. Thus one can only drive with the bright lights on, causing a lot of angry motorist. The folowing procedure is followed: First the master light switch is turned on, then the dip switch (combination switch) is moved from whatever location it was left in and the bright lights come on. If one then activates the dip switch the bright lights go out but the dim does not come on. Hit the dim switch again, and the bright lights return. Any ideas what is causing this?
