My 1998 Mercury Grand Marquis headlights as well as tailights fail. During this all of a sudden while driving at night the headlights while driving will start flashing on and off, then just completely go off, as well as the lights on the doors and light around the dash controls such as (ac buttons an knobs) this happened rarely, but now it happened every single night. I googled this and many more are having the same problem, it seems as if its common in these vehicles. On the forums some say a light control box needs replacing, and then some say a headlight control module needs replacing. This needs to be investigated. A recall needs to be filed for the replacing of the bad part causing this issue. This can cause serious injury to someone if this happens on a dark windy road.

Consumer states that the exterior of the headlights are fogging up, causing poor visibility.
Was traveling about 60mph on a paved country road, when headlights went out without prior warning, dealership was aware of problem. Consumer stated lights flashed on and off several times, the lights were then turned off and turned back on againg, they flashed about 2 more times and then remained on.
Headlight lens deteriorated and caused lights to project poorly when used. Dealer notified and refused to assist in this matter, asking NHTSA to look into this matter.
The same condition happened on 12/99. I reported this to the service dept. At bill smith Ford and they replaced a part that controled the high beams. It happened again 11/99 driving on hwy 85 at approx. The same area. Both times I was driving at night (11pm) with the high beams on when without any warning all the lights went off. I turned off the high beams and the lights came on. I believe that this is a serious problem that you should investigate. I have an appointment to have the car repaired.
When headlights are needed at night or in rainy weahter conditions headlights are very dim, causing poor driver visibility. Also, note headlights look like fog is in the bulbs. Consumer has replaced headlights; but, problem is still occurring. When the head light assembly was replaced, the problem seemed solved, but the plastic lense cover fogged up again. Also the low beam lights appear brighter than high beam.
The high beam indicator light is the same color as the rest of the light thus making it hard notice when high beam are on.
