I own 2014 ford fusion SE with halogen (H7) headlights.
There is a weird issue with drivers side lamp - sometimes it randomly flickers a bit and because of this reason bulbs go out fast. Bumpy road doesn't increase the flickering, however, if I turn on turn signal then flickering intensifies and becomes very obvious.
Has anyone had this issue? The generator works fine and outputs stable voltage and passengers headlight works fine as well. I have changed bulbs a few weeks ago.
