Electrical on 2004 Ford Taurus

The parking lights come on periodically after the car has been parked, key removed, and light switch off. (Light-on alarm also sounds.) Removed the light switch, but continues. The only way to turn off lights and stop warning, is to remove fuse. However, the battery is being drained. Had battery checked and it's OK. (Battery is approximately 1 yr old.) Any suggestions?

Do you have a factory or aftermarket alarm system that will flash the park lights? If you do that is where I would start looking for your problem. The other option would be to try and chase down the cause of your drain, that may lead to the cause of your lighting issue.
