as far as i know this is a new one. after driving the car for about 1/2 hour and shuting it down i get a sick buzzing sound from under the dash or the same place as the "lights on" sound. it kinda sounds like the old emergency broadcast sound on the tv. i doesn't go away until i start the engine and turn it back off. it's is an electronic sound not a rattle. any ideas? the car is stock/touring. vin 7000's.

 

Thats ur HID light. Its normal
