Review on Partsam Marker Surface Waterproof Utility by Alex May

We spent about 4 hours fitting them properly onto the myBoat trailer. If you tighten these caps more than lightly, they will tear and your "watertightness" will disappear. Even those that don't have cracks aren't waterproof. When I put them in the water for the first time, they are half lit. I tried to lubricate the covers with silicone to protect them but it was too late. Tried to contact seller about the problem, may have sent several replacement parts for the faulty ones but received nothing. Spend the extra money and get better light. I've put a lot of time and effort into them.
