Submersible Trailer requires light to be "tight" or "watertight". Used 1 time in a lake and water got into one of the two rear lights. Still works but the light is blurry and not what it should be. When you buy and install them, smear some silicone around the connection between the lens and the body to seal it. They don't appear to have a factory seal or sealant and just snap together. Thought a removable drain plug would probably be a good idea, if they can't keep it dry at least get the water out!
