I have an '06 F150, with the automatic headlights. If the lights were on when the truck was turned off and the keys removed, when the door is opened the headlight warning chime starts to sound. It will continue until I dim the dash lights with the roller switch on the dash. After the dash lights are dimmed at least half way, the chime stops. This just started in the past week. Has anyone else had this problem, or have any ideas how to fix it?

Thanks in advance
David
