I installed the same lights in a friends boat a few weeks later. We cleaned his really well and the tape still didn’t hold well in a few places. We ended up adding some 3M Auto Exterior Attachment Tape that’s used for securing body trim to the lights and it holds much better than the tape that comes with the lights. I’d suggest getting a couple of rolls of this and using it on the initial install. If not, definitely make sure you have some on hand for repairs when the other tape fails.
