This is a simple way to add a permanent trouble shooting light to the Engine bay under the bed. I found that when I most needed a light in the engine bay during times of problems, the standard LED lights and flash lights did not work well. These lights were constantly falling over, or falling under the coach or shining in my eyes. I needed something fixed but movable in a time of possible emergency or just basic work so I added the LED lighting system in this presentation. There are two LED lights, one mounted to the bed that turns on when the bed is lifted, the other is also LED but has a 120v plug-in and can be moved to any location desired
