My suggestion is to use a manual switch to turn them on when they're needed. At the same time set up your back up lights on your truck with a manual shut OFF switch so you can actually USE the lights on the trailer. Back up lights reflecting off of the front of the trailer will KILL your night vision making the trailer back up lights next to useless. You'll be surprised how much difference it makes to get rid of the trucks lights when backing.
X2. There will be times when you don't want or need to use them. I have Bargman tail lights and they produce enough red light to be able to safely navigate at night. Best of all they have little effect on night vision.
