They do look good. I wouldn't worry too much, the area where the light sits shouldn't allow for any water to enter in. If it did they would have a different design that would be more air tight so water wouldn't slip past. It would likely just drain down and fall under the bumper and out onto the ground.

If it bothers you that much, I would call the company and see if they can replace them with a set not "mis-shaped". Otherwise, just enjoy.
