I've had them on my SUV for a few weeks now. I bought two sets. blue and yellow. They are mounted on the grille at the front of the car and on the sunroof at the rear. Both are outside the car. We have had rain and there is no sign of water on the light or around the seal. They are very bright. Probably too bright. They are good for running during the day but will blind your eyes at night. I have recommended these lights to others in our industry. You need to buy cables and switches. They only come with light. Still worth the money!
