I didn't think ape-goo would dissolve an LED.
24V will.
BTW, off-topic-- if you use RTV (silicone that smells like vinegar), don't put voltage on it, certainly not high voltage, until it is totally cured (stops stinking). I did, and the RTV smoldered then burst into flame. You have to wait for ALL the water to cure-out before it gets non-conductive.

I have been using Hot Glue to hold LED's for years. Holds well and can be removed without too much trouble. I usually use the low heat or duel heat versions.
I suppose it depends on the definition of 'plastics' but many man made materials are attacked and dissolved by superglue.
You cant beat a dab of epoxy imo for securing something like an LED. RTV sealant needs to be the slow curing type. If it smells of vinegar then it is the quick cure type that uses acetic acid and that can attack metals (components/leads etc) over time.

Edit... hadn't turned the page 🙂 Only just seen PRR's take on the RTV stuff. Do you know, some repair techs used to use that stuff for 'sealing' arcing LOPTX's and final anodes on CRT's. Scary.
Actually with one's wits engaged.. Drill the appropriate sized hole so the LED will friction fit.
Hot glue. If you ever need to take it apart, you heat it with a hairdryer until it softens enough to remove. Epoxy will work and not harm the LED or panel but it takes longer to cure. Devcon plastic welder or JB Weld would work also but once glued is not likely to come apart. JB is nice because it's water soluble before it hardens.

Don't use Duco cement -- it's a nitrocellulose cement with acetone, isopropanol etc.and will dissolve many plastics.
I was at a meeting with a Chinese furniture manufacturer visiting our facility. We were told he didn't speak English. My partner asked the translator what they used for imperfections, and the boss inadvertently and immediately blurted out "Bondo". You could readily re-seat the LED with a Bondo plug.
For about a dime you can also get a split gasket, which might work aesthetically.

You could even wrap some teflon tape around the rear portion to build it up enough to fit tight.
