How to re-seal fiber led tail lights

Was wondering if anyone had videos, explanations, tips, etc on how to re-seal fiber led tail lights. There CG fiber led that started leaking RIGHT after the warranty period.
Any and all help is welcomed!

Go around the area where the lens plastic meets the outer edge with clear silicone. Always worked for me. I did that immediately with my aftermarket tails after seeing there was literally no weatherproof seal between the lens and housing.

This should work:
