GREENSBORO, N.C. – Wendell Grisim was looking for a nice used car. He checked out a few different makes and models but eventually found a 2014 Cadillac at a used car lot. The car was working well, but Grisim started to notice the headlights seemed to be dim when driving at night. He wasn’t too concerned but it kept getting worse, so he decided to take the car to a repair shop.
