So among the 14 error codes I have after a head on collision is front left and front right headlight not working. The housing is somewhat banged up but I'm slowly but surely rebuilding this car. I got a wiring harness for each headlight and took the headlight apart and put in the new wiring harness and new low beam bulbs but they still don't turn on and I'm still getting the error messages in the dashboard. I was reading something about a ballast, could that be the problem or does anyone know why my headlights wont work?

I appreciate all the help you guys have been to me
