Reverse lights, camera, and shifter light always on

Today, no matter what gear I put it in including park, the reverse indicator on the shifter is always on along with the reverse lights on the rear and the camera. I was driving and it just suddenly came on. Everything seems to shift and work right, no check engine light or other problems. I had it in four wheel drive and parked it a week ago and just picked it up today in Oklahoma City, took it out of four wheel drive and headed to New Mexico and had driven about three hours when it happened. Not a high mileage truck. Transmission fluid looks good. It was been in a minor front end accident with a deer in November of 2011. 4.0L V6 EFI SR5 double cab. I stopped and put it in an out of four wheel drive, but nothing has changed. Any ideas? Thanks

 

I would look at the rev switch or for something holding it active
