Barracuda tail light swap

I would say: mount it in the most indestructible location so when your friends or family borrow the trailer you have a chance at the light still being there if/ when it is returned! LOL (sore subject with me and my flatbed can you tell?) If the light is primarily for plate illumination I would think above the plate/ furthest from the ground possibly facing down to illuminate the plate? Hard to know without seeing how bright it is at night. Maybe one hitting the plate and one shining back for BU lighting. How do they mount Matt, 2 sided tape?
