You're saying they are falling due to their weight?
I have a 2016 3270RS BH with the island lights and have never had an issue. I don't believe they are that heavy, If I'm understanding you right, I wouldn't fix something that isn't broke unless you just want a different fixture. Every new rig has its Gremlins. There is going to be plenty of minor repairs to be made sooner or later. Just because one rig has an issue due to a bad build doesn't mean your rig will have the same issue also. Good luck in your endeavor.
