ECCO’s 3rd brake light platform for LED brake lights is constructed with durability in mind for even the toughest of jobs. The platform mounts behind the factory 3rd brake light and clamps to the body opening and the factory light is then reinstalled over the mount. The design meets the demands of heavy-duty applications without damaging the vehicle and enables mounting of products such as beacons and worklamps to the top of the truck. This mount is designed to fit aluminum body Ford F150, F250 and F350.
