Re: [diesel_mercedes] Interesting headlight problem

 

No. the low beam has a higher resistance than the high beam. If the ground is out or bad then the power will try to find a ground through the lower resistance high beam filament. The high beam is a lower resistance and looks more like a wire than a resistor. So the bulk of the energy will be burnt up in the high resistance low beam. And since both filaments on that side are now in series along with the high beam filament on the other side, before a ground is found there will not be much current flow and only the high resistance low beam will glow. And it will glow dim.
