The lights are well built and completely watertight. These provide a very bright flood light that lights up about 50 yds forward with a wide and tall beam of light. They are not to be used with oncoming traffic because it will blind other drivers. They are perfect for off road and dark deserted roads. I would highly recommend the brand, and the type of lights. I put them on a Ram 2500 with a HD steel Bumper and they were easy to adapt to both the bumper and the original wiring harness connectors.
