While driving on the Massachusetts turnpike at night the headlights shut off with no warning, notice or anything. Never had this happen before. Scared us to death!!! we immediately turned the signal to pull over to the shoulder and then they came back on. About 2 minutes later they went off again. My boyfriend pulled over to the shoulder and turned on the hazard lights and shut the car off. We then turned the car back on and had no headlights, just marker lights. But, if you held the stick for the high beams you could use those. Then the lights miraculously clicked on and stayed on for the rest of the way home. This has been a continuous problem. After much research I have found out it is the lighting control module. Approximately a $650 part and about $200 for labor. I contacted Ford Motor Company and they do not feel that this is a safety issue and are going to do nothing about it!!! really!!!! I am part of a website and I get numerous emails for people that have the same problem. I am afraid to drive at night because I never know when the lights will work or not. I don't want to blind people driving behind them and it just really sucks that Ford does not think that driving down the road at night with no headlights is not a safety concern.... why doesn't the Ford executive try driving home in the dark with my car and see how he likes it. Then we will see if it is a safety issue or not, huh??

While driving at night, the headlights suddenly go out. This is very dangerous, regardless of either driving on the highway or in the city (especially with pedestrians). They tend to stay out for 10-15 min before they start working again. While they are out, the brake lights go out at the same time, making it even more scarier, cant see to drive, and the car behind me cant see me slowing down or stopping, which increases the chances for an accident. Needs to be recalled asap. It appears that it is the lighting control module is faulty and the part itself is quite costly starting at $300 - $500 for the part itself or $800 installed.

Grand Marquis 8-cyl

  • 83,118 miles
I was returning home with my wife from a trip to charleston, SC, at about 10:00 pm, driving at 60 mph, when my headlights suddenly shut off. That happens in the vicinity of awendaw and there are no street lights in the area. Both my wife and I screamed in panic while I was trying to slow down the car and staying in my lane on the highway. I was thankful that the turn signals, marker lights and brake lights still worked, so any other cars would be able to see me. When I finally pulled up the side of the road without any mishaps, I inspected the car and found out that all the fuses were good. I then restarted the car and still did not get my headlights to come on. I played with the turn signal/ low beam/high beam lever and got the flashing high beam position to work, so I drove home to myrtle beach holding the flashing high beam lever up to light my way. Otherwise, I would have to hire a taxi, spend the night in the nearest hotel to wait for daylight to resume my trip home. Apparently, the problem with the headlights shutting off without warning while driving at night comes from the lighting control module installed the 2005 Mercury Grand Marquis that malfunctions when the cars reached an average mileage of 69,000 miles (some as early as 30,000 miles, up to 114,000 miles documented).

Headlights go off, tail lights and running lights stay on. After slamming door or slamming hood lights would sometimes come back on again for a while, then go on and off at random with light switch turned to "on". checked all fuses and relays I could access and all were ok. Has acted this was for three weeks now. It's dangerous to drive at night.
