FWIW, Just this season our Yacht Club equipped both of our launches with Lopo Lights. They were installed by the Landing School and installed correctly. We have had multiple failures and it is only August. I think at last count it has been four failures since installing this past spring. Don't know what is going on but it's not good. Lopo keeps replacing them but we now have those cheap flashlight running lights mounted to both bows. Considering the price paid for the Lopo's we should not be running "flashlights"..
