I have an ongoing intermittent problem with my exterior lighting. Occasionally, the front right amber light and the entire right rear light assembly, along with the license plate light do not work. Sometimes, if I turn the car off and on or repeatedly turn the lights off and on, all the lights will come back on. I have had the car back to the dealer several times, and they even changed the light switch on the steering column, but the problem still comes back very intermittently. I have blue LED's light bulbs for the license plate and wonder if this could be the problem. There are no codes being thrown according to the dealer. I searched this forum but didn't see any results. Any ideas???
