Jay, flipping the lights is really easy, but you do need to fab a plate to mount them on. I used some very light weight metal. Drill three holes, two for the ROP mounts and one for the wiring. My first version, on one side I used two pieces of the light weight metal and I ran the wires through he seam between them. the other side had a single piece with the three holes. The two piece version metal fatigued due to vibration and cracked.
The secret is the lights must be reversed left to right, and use just enough metal to stabilize the lights. Too heavy and the lights take all the abuse and not the mounts. Yes, they still will take a hit now and then.
