Default Glue for plastic to plastic?

I'm working on replacing the burned out incandescent pilot lights in a '70's receiver with white LED's. Obviously, the mounting technique of the old bulbs will not work for the LED's.

I think I would just like to use a soft glue and plastic washer to hold the LED to the plastic where the bulb had been. Need something that should not harm the original plastic, and should cover gaps.

I'm thinking hot glue might damage the plastic, and epoxy might be so strong as to cause damage if the LED had to be repaired. I think silicone would do the trick, but thought I would ask the question in case there's something better.

Hot glue does not damage plastics,, it neither has solvents nor it gets *that* hot.
For easy removal hit it with freezing sprat which makes it fragile (while cold) and crack it away.

I would use hot glue as well.
Silicone is finicky and doesn't like sticking to some plastics.

+1 for hot glue. Just be careful with the hot snot.

Alternatively, a marine adhesive might work. They're usually similar to contact cement in that they stay somewhat flexible after they set.

I used hot glue to replace the meter lamps on my old Phase Linear 700. Worked great.

I've used Loctite 406 with some broken plastic center console facia surrounds etc in my old 1993 Nissan Skyline. Glues instantly, excess can easily be wiped away because its anaerobic and only set when there is no air present.
