2012 Cadillac cts low beam lights do not work. High beam and daytime running lights work fine. I changed the bulbs and got the same results.

  • Vehicles come with a low beam fuse, and a high beam fuse and from what I've seen some cars are also equipped with a bulb relay... check to see if you're getting power at the end of your wiring harness
