I should have confirmed my understanding with Carol. I bet the waters running behind the housing, into the trailer and my Scamp
Problem is the darn butyl makes that plastic housing so tight I'm afraid I'll snap or crack it.
Now this time let me confirm: to seal the black housing to the trailer Carol, should I just run a sausage of butyl all around the edge of the housing? Should I still put over screw holes and around plastic lens as I have now?
Some might advise me to do a water/hose test but I won't do that till I'm sure my bases are covered.
Wendy I would just do a line of butyl about 1/2" wide on the trailer at the point the main light
housing sits on the trailer, leaving a bit of a gap at the bottom to allow any future moisture to escape
on the off chance it gets in. My experience has been with the trailer not being flat there are various sized gaps between the light
housing and the trailer surface. Take a look at the light
before you remove it to see where the biggest gaps are & make the butyl thicker at those points and thinner at the points where it already sits snuggly.
If your worried about cracking the main light housing while screwing it back on - best to screw it back on slowly - do at little bit on one screw at a time - don't screw just one screw in all the way and then do the others
. Just get the light in place then slowly tighten each equally going back and forth between the screws until it is firmly in place and equally screwed in with each screw and you have no gaps between the housing and trailer.
It would not hurt to put a little on the screw holes as well but if its well sealed around the top and sides on the outside edge of the light housing that shouldn't be necessary. Once you have the light housing mounted back on the trailer just trim away the extra butyl. I don't think I would bother with doing any around the lens itself unless you think that is fits loosely at the top as well and suspect the water is going into the lens and filling up and the water is seeping through the wire hole into the trailer .... which I suspect is not whats happening, mostly likely seeping down the back of the light housing and dripping down the wires into the trailer.
Hope that helps.
