“I was driving my 1994 Mercury Grand Marquis gs home from work one night around 12:00 am and I experienced total lighting failure. All of the sudden everything was pitch black no lights what so ever. Every light on the car would go out and come back on simultaneously,causing me swerve, almost crashing head on with oncoming traffic. I have read online of other Grand Marquis' and ford crown victoria's doing the same thing.this was only my first experience with the lights. I have owned the car since jan 23,2013 and the lights continue to do this therefore I cannot drive it at night. …”
