Tail lights

Problem was or is they never solved the fundamental problem there is a gap sealed with a open cell foam, which like a bath sponge.
They tried to be clever by adding the screws to try and increase the clamping pressure, but that doesn't work.
Unless you glue up those seals it will leak again.

Hi Flybobbie

I took the seal to a bearing/seals company..they said its a closed cell foam seal designed for low clamping pressure..they offered a couple of expensive gasket type sealants to augment the seals..

I'll give my old units a good re-furb, test them, seal them up and then either ebay them or offer them on the forum (asuming they keep working)

I would say they are incorrect on the type of foam. We used a lot of foam on traffic light equipment that had to be closed cell, that would not absorb water. We had a batch of wrong foam and had refit a load of sensors where capillary action had drawn moisture into the units and corroded circuit boards.
The seals on these lamps you can wring the water out by twisting, in fact i would start to dry them by pressing them between tissues. When i fitted my seals with glue i actually squeezed the rubber and it would soak up the glue, good really.
Don't use silicone it doesn't seem to stay attached to the black plastic.

All i can say is my other "new" lamp which was glued up 4-5 years ago has never had any moisture in it.
