I don't drive my 2008 F350 diesel everyday, but lately I've been driving it more. Lately, I noticed that the 1st gear indicator is always dimly on. It's dimly red even when the engine is off and the vehicle is locked. The truck drive fine and doesn't have any issues. I'm worry that this will eventually drain the batteries. When the truck is running the red light behind the 1st gear indicator is dimly on. Here is a picture with the vehicle in park. Any help is appreciated.
