Walked out to my truck tonight and saw that my parking lights and dashboard lights were on. The switch is switched completely to "Off" but they stay on. The headlights stay off and they will come on once the switch is turned. I drove it home and the same thing. I guess I'll have to disconnect the battery or pull the fuse for now, but does anyone have any insight?

Thanks

Check the headlight relay. If contacts fused together...they will stay on. :(
