My head light going on and offf and not bright

Your switch is the problem. It's a bad ground or short.

The Lincoln in the automatic light mode will turn your brights on our off depending on brightness or if a car is coming, nothing is wrong.

Headlight goes off and has to be turned back on while driving what's causing this

Ballast???

Did you figure out the problem? I got the same thing happening To me. The passenger side headlight bulb turns on but its dim, few seconds later turns off I noticed I can turn it back on with the switch but turns off. I’m starting to think is the bulb?

My right headlight stay on when car is off an when i Turn car on an put lights on that light is out on right side

same problem, was gonna switch the switch, Lincoln said it is most likely a ballast.

My 2009 MKZ has no low beam on the drivers side. Ballast was burned out. Got a replacement ballast and that is burned out, too. Mechanic wants to replace the entire headlight assembly! Please help!

My 09 Lincoln Mks passenger headlight goes out every time it rain and it's also lose
