It's very common, I used a black silcone from halfords I had, I know it's not the best, it's fixed the issue but I know if I want to remove the lights it is going to be a pain, there is a load of threads on here, with the right product to use, it's a non setting Sealent

When I got my car it had L.E.D rear lights, I also went back 2 standard, Best thing I could say is clean off any old sealer etc and use some tiger seal to put the new ones in, and you should be ok, I aint had no leaks since.

Thanks 4 the advise is tiger seal like a silicone sealer that goes off (sets) on the standard lights I put in there was sum kind of sealer on then like play dough u could mould

For God's sake DO NOT use Tiger Seal, Sika-Flex, or silicone. It will seal them, OK, but you will never get them off again...what happens when some idiot in a supermarket carpark busts one for you???

The correct stuff to use is this:http://www.ebay.co.uk/sch/i.html?_tr...at=0&_from=R40
It's a non=setting mastic.
Clean off all the old stuff from lights and car: old screwdriver, lolly stick, white spirit and patience.
Squeeze a 10mm bead of Carafax around the light, and press firmly into place, replace all nuts. Job's a good'un, and the light CAN be removed when/if necessary.

NB: you might need to buy a sealant gun suitable for 400 ml cartridges, Screwfix, Wickes etc. The usual ones are for 350ml.

Yh mate tiger seal is pretty hardcore stuff, The reason I used it was I couldn't find anything strong enough everything just turns 2 mould like you said.

But alcazar has a good option you should go for that

Did u put the carafax around the studs on the light units?

Plumber's mate is similar to Carafax, but tends to produce a non-sticky surface after a time. It also comes in a tin and is messier to apply
Carafax is MADE for bedding stuff like awning rails onto caravans. It won't go hard, it won't set, it remains sticky, you can remove and refit the lights at will.

I didn't put any round the studs, just on the bit where the light meets the bodywork, which is clearly defined on the rear of the light unit.

Not had any problems. It wouldn't hurt to put a thin circle around each hole on the outside, before seating the lights.
