My WRX is stock. I have had it for 4 years and only had minor problems. The other day someone told me that I had left my lights on. This is imposible because my keys were in my hand. I went out and sure enough, my tailights and parking lights were on even with the car off and the lights turned to off. I pulled the #5 fuse which only goes to those. I have had to put it back in to drive home from work the last couple of nights but everything else seems to be fine. Any ideas?
