Leak to rear tail light - Led light sealed

UnsureAboutthis

Leak, and water inside the rear tail light. The light is LED and sealed.
I've taken off the light and there are no bubble holes etc to drain the water just an electrical connector.

(The car was purchased a couple of months via private sale ago, a 17-plate, one owner, FSH and done 89 thousand miles. - The car has not been in any accidents)

I've been looking for hours for the correct/best glue or sealant. However, the sealants that appear to be good often state they are not suitable for plastics/polycarbonate etc.

The seam between the red cover and the grey plastic of the back of the light is very slim. Therefore it may be not easy to apply a sealer.

I've considered and shortlisted two sealants both non-silicone. One is Evostick, stick like s-ht and the other is stiksall. 

I've also searched the net for a repair specialist. There are a few for headlights but none for rear lights and the costs are high.

All ideas and suggestions are appreciated.

How about this one - it is different to the ones I liked earlier. Its is UV resistant.

I had this on a BMW front light after someone knocked the side of it cracking the seal. I used low modulus glazing sealant from screwfix and it seems to have worked. I think the low modulus means it is less stiff when it sets so less likely to fail.

We have just had ours done as it is a sealed unit and had water ingress. 

I as expecting a big cost but took it to the local garage who ordered the replacement unit and fitted it. Cost just under £90.

Yes, I read it as a "flexible" sealant.
Which one did you buy, do you have a link?
I'm looking at outside/inside sealers and my second post, the sealant can withstand high and extremely low temps and is UV resistant.I appreciate your time.

Its a Volkswagon Golf Luna Plus and yes it was the rear led light and indicator.

My son's Fiat Punto has combined LED and normal rear lamps which got water in them. I just drilled a hole in the bottom of the lamp housing to let any moisture escape. They've been fine for the last 6 years.

Thanks - I've read on the net about others doing that and it worked.  The problem with this car is when I looked at the blown up pictures there are cirut boards near the bottom as it is fully LED.

How big is the hole you drilled? Sill question but the light unit is long and big  - I was thinking 1mm would be too small and 5mm too big and possibly try a 3mm hole?
