Sealing lights

[AcID ZeR0]

I've brought some aftermarket Red LED lights (not lexus type) they look quite subtle so I'm pleased with them.

Only problem being they like 99% of all aftermarket lights let water in, makes my old Clio's sunroof look waterproof lol.
Okay it isn't that bad but what I mean is when I washed the car there was water around the edges under the perspects(spell?) and I'm guessing that will condense(again.. spell) in the winter?

Any ideas how I can stop this, minus the bin them remarks thank you very much

sounds stupid but what about clear silicone sealant> take the light out. Plaster the back in the sealant to make a join and then put it back on. That will create a watertight joint that can be broken if ever you wnat to get the lights back off for bulb changes etc.
