since im new here, i cannot post on other item specific discussions and I need help for my ride ASAP. My Cadillac Brougham 1987 has some problem with the headlights but im not sure about the specific problem if its the wiring or the part needs replacement. Headlight doesn't turn on low beam but only lits up when set to high beam. However, there are times its not working at all. I want to try and fix it by myself than going to a mechanic.
