So tonight I was driving my 2005 Ford Crown Vic P71, on a dark road with all my lights on the street had no street lights then after getting to my destination I turned off the lights and car then when I returned I found that the parking lights went on but both the low beams and high beam headlights were not working, I looked over the fuses, but they all tested good, any suggestions?

Thank you, please help me soon with your comments..

iT COULD BE THE SWITCH ,LIGHTING CONTROL MODULAR OR BOTH BULBS WENT OUT . I WOULD START WITH A LIGHT TESTER AND START CHECKING IN WIRES FROM THE SWITCH TO THE BULB.

Could this really be, as the car is only 5 years old, I thought maybe a fuse or something simple?? No?? If i take it to a mechanic can they trace it down pretty fast?

Definitely the LCM [lighting control module] and one of its relays. If you can't find the relays, or don't feel comfortable soldering, then you can pull the LCM and send it to Airbags [on eBay] and they will repair it for $53.00 [permanent repair]. Note: car won't come out of park without LCM in place...so, you'll have to wait a few days to use the car.
