The sticky part has already given out and they aren't staying up. Glue, reef safe double sided tape? What. Should I use. Wanted to be able to remove them if I need to so I only want to glue them if I can't figure anything else out.
That is a link to my RSM 250 thread. Those LEDS have been there now for a year. Buy at the hardware store exterior double side tape that supports several pounds. Usually is a Red tape. Attach it to the plastic hood using the tape, as much as you can. Apply over dry plastic.
I am happy it worked out. As you can see I have a first layer of double side tape in between the strip and the hood. That is the classical way. But to reinforce I added small pieces of tape on top also (you see the red plastic that covers one of the side ). So far so good.
