Hi,
I have those and mounted them 3 years ago left and right on to the chloroplast.
They supply 3m tape on them which seems very durable.
I just put additional Gorilla Transparent Tape over them to secure and protect them.
Its great to see critters at night.
Especially while boon docking.
I also think as we do not see critters the light keeps it away.
If we are at a tight campground we also turn it of when going to sleep.
Love it
Mike
