“Hmm, it is dificult to review an o-ring, a seal. I hope it will work, it looks it fits well into an anchor light housing. I was thinking of 2mm profile but it could be too much. I even do not know what was there originally as it perished with no trace.
To be honest, anything like this require time to say anything about such product. Today it fits well and I hope it seals the same well, so water will not be able to ingress. But this is all. I wil be able to say more next year, at leat find our if it is still there.”
