Looks like I have water in the second to last cross member in the trailer right below the lights. Not the rear member, the v cross member right behind the axle.

i saw some rust on the trailer around the light and thought it was strange , so I tried to clean it up and realized when I moved the light slightly rusty water would come out. So I pulled the light with the rubber gasket and about a half gallon of rusty water came out. It's been in my back field for a week now.

Not sure how it got trapped in there, when I examined the wires , the protectective coating is stripped on one side from being pulled through the trailer. Not good if sitting in water for long periods of time.

any thoughtson how this should drain or not fill up.
