2015 T660. Reverse lights

[Mattman]

Truck in neutral, key off position reverse lights are on. Noticed while unloading they were barley shining, like what is going on. Cycled key, still on.

Drove about 150 miles noticed twice while changing lanes blinkers would blink faster than normal, right or left it didn't matter. Blinkers blinking fast doesn't happen each time I use blocked.

Got stopped for my 30 minutes and reverse lights are still on?

Any ideas
