Curly one for your advice

Yeah I know Ive already been called stupid etc but this is my plan

These are aftermarket tail lights I would like to fit into angled PVC pipe (so the lights are vertical to the road. They do come with an ugly big black grommet that I really dont want.

I want to find a way to fit these inside the pipe (which will be fiberglassed) but be able to remove them if needed.
Have thought of hot glue gun...would that still hold in extreme temperature?
Silicone...hold them in but removing them???

Assuming you can still access the lights from the back of the PVC pipe once they are fiberglassed in place...

What about a couple of small 'right angled' L-shaped metal brackets?

One side of the metal bracket could be glued with Araldite to the back of the light casing towards the outer edge.

The other end of the bracket could then be screwed to the inner wall of the PVC tubes using a nut and bolt.... with the nut inside the tube.

To remove, simply use a small spanner to remove the nut in a slot cut into the bracket, so it slides off the bolt.

[.:4:.]

Well, my immediate thought would be add a threaded coupler and cut out the centre of a threaded cap to so it acts like a retaining ring but that would probably look crap.

lateral thinking..I like that, give it a try anyway.
