LED Trailer lights - Does the seal matter?
 

I'm putting on a pair of Road Warrior By SeaSence LED trailer lights and out
of curiosity I placed my bubba lips over were the black plastic molding
meets the red and sucked. In several places there was air coming through. I
should take some clear silicone and seal it all around. does it really
matter when there's no wiring to get too? It's in salt water most of the
time.

Thanks SC
