The headlights went out while my son drove to get some last minute food items for Thanks Giving meal. All other lights work, only the headlights will not come on, including high beams. I have checked the over heat breaker that is attached to starter relay on battery side; it is good. Checked an inline fuse that came off of same post as breaker, that had a similar coloring as wire off of breaker; It too was good. Unfortunately I haven't a lot of time to put into my Lincoln, although it is my favorite ride, so I thought to ask for some advise. Any advise is apricated.
