I'm sure there are other good reflective tape manufacturers but this is a case where you don't want to cheap out, big difference between cheap and really good tape. Years ago I had a retired Ohio Highway engineer tell me to only buy 3M reflective tape, that it was the best and that is what I have on all my trailers and a strip visible under my slide in camper on the truck. The tape lights up like it is a powered light when any light hits it, much more attention getting than any lights or small reflectors that you can add. On his recommendation I have orange/white stripes the full length of my trailers, low on the sides and red/white stripe across the back, again low. Higher would probably be better but this is a compromise between appearance and visibility. You see the stripes much sooner than you see what they are attached to.
