I added some rear LED lights onto the bottom rear frame rails under the bumper. This solved the backing into darkness problem quite well (it almost looks like daylight in the dark) and are low enough power (36 watts total) to work on the same back up lights circuit without overloading that circuit. Less than 25 bucks on Amazon. Signstek LED for any who might be interested

 

Are the ones you have? Can you post pictures? What is the best place to get the power from?
