When it comes to tail-lights some states have requirements as to how high they have to be mounted. Check your state requirements before mounting. 

This universal tail-light wiring harness will work with every car being towed on the market today, or be used on any trailer.

Each L.E.D. strip mounts under the rear bumper with provided 2 sided tape. Then fasten the wire up to the bottom of car or trailer chassis with provided zip ties. Keep in mind the wire is longer than the car/trailer. But make sure the wires are long enough to hook

into the back of your motorhome/truck before mounting the excess wires up under the front of the car or trailer.
