Tail light gaskets

I've noticed water getting into the right rear tail light of my Alfa 164 (cue blinker fluid jokes). I haven't had a chance to remove the tail light to see where it may be coming from, but in any case the gaskets are probably hosed at this point. What sort of materials would you guys use to make new gaskets? Anything I can get at PepVanceZone? I added a picture so you can see what they look like.

I have used volara foam and the universal weatherstripping that lowes sells. Both work well.

Are new ones still available? I recently ordered new new ones for the 911. They weren't that expensive.

I'd look for OEM gaskets first before making my own.

I use 3M strip-calk for obsolete light gaskets. You can buy it at parts stores out of the paint and body section, or lately I have ordered the Eastwood brand strip-caulk and found it to be equal to or better than 3M variety.

Here is an example of using it on an old pair of antique fog lights where I had no hope of finding replacement gaskets.

No separate OEM gaskets are available for the 164 tail lights. NOS tail lights for the 164 are becoming scarce but I know where I can source a couple, plus eBay is littered with used tail lights. I may need to replace the whole assembly anyways but at least if the plastic is intact I could make some gaskets for the old ones and keep them as spares or sell them.

That will be helpful in case the lens seal is broken instead of the gaskets on the rear of the lenses being worn out.

If new gaskets aren't available, I agree with the opinion on 3M strip caulk - it's good stuff.
