What makes a car’s running lights go bad?
by Richard Rowe. Headlights are power-hungry devices. Combined with the headlight’s inherent visibility, this attribute will often make a car’s running lights the first components to suffer from electrical system faults. These faults can range from a bad ground, to an failing alternator to a simple abraded wire.
