How to seal a leak

Thanks for this forum, although I'm a little older then most, I continue to learn through your posts.
I've have a leak in the front of my trailer, and after searching your post, it was recommended to check around the running lights. I checked my upper marker lights and sure enough it was never sealed with caulking. My question- do I go all around the marker light with caulking, or leave an small opening on the bottom to let any water that might get in leak out?

Just putting a bead of calk around the light is only a temporary fix. In order to seal them correctly you need to remove each light, clean the area and the lights thoroughly, then seat them in a bed of butyl rubber or better yet use Eternabond double stick tape. After re mounting you can then put a small bead of butyl around the fixture. Do not calk the covers to the fixtures. No need to leave a path for the water to escape if you don't let any in.

I would remove the lights, apply sealing putty behind them, screw back down, then silicone around the top and edges, but leave a spot at the bottom for water, like you said.

leaving an opening at the bottom of clearance light could cause water to driven up and into if travelling in rain.

There is no need to seal around the outside of running lights if you seal the wiring access hole in the trailer and the mounting screw holes.
When I discovered my running lights accumulated water inside the lens, which then followed the wiring inside the trailer, I drilled a 1/8"hole in the bottom of each lens to prevent future occurrences.
DO NOT USE SILICONE, IMO silicone is not a good sealant for RV's. Dicor non-sag sealant is the best option for this application. When removed silicone leaves a stubborn film that nothing else (not even new silicone) will adhere to, requiring the use of a special silicone removal product.
