Hi everybody. Out of nowhere my 03 X5 has started having light issues. When I start the car the head lights and brake lights stay on, the fog lights don't work, the light module doesn't work, the emergency lights don't work, and the turn signals don't work. The radio does work, the power windows do work, the visor lights even work. All the fuses are good, all the bulbs are good, tried changing out the ignition switch but didn't resolve the problem, tried disconnecting the battery for an hour (which worked the first time and all the lights were back but then within the same day they all went out again and disconnecting the battery didn't work again), the battery is new, there's no water damage, the sunroof drain is not clogged. I really don't know what else to do. I appreciate any input. Thanks!

Sounds like the LKM is toast. You should go have an indy/dealer scan the cluster memory for LKM error codes. An OBD II scanner will not show these codes.
