Tip for Preventing Leaks When Installing Optronics Light # MCL67RB
Updated 11/02/2026 | Published 11/01/2026
Question:
I installed these lights on my DIY camping trailer on the roof in the rear. They leaked and made a mess. I used silicone sealer on the outside but did not put sealer underneath the lights and they dont come with a gasket. I am cleaning things up and about to try again and would appreciate advice on how to do a better job this time. Thanks.

Hey Robert, welcome back! Sorry to hear about the Optronics light part # MCL67RB allowing water in. I would try putting the sealant around the mounting holes before placing the bracket so that the holes are nice and sealed up as that is where the water would make its way in. I would then also add sealant around the base as well again to help there as well.
