The LED 4 round stop/tail/turn light is designed to conform to applicable US FMVSS108 and Canadian CMVSS safety standards. It contains high-output LEDs for exceptional brightness and performance on vehicles over or under 80 wide. The life of a LED light far exceeds traditional incandescent lights and draws significantly less power than traditional halogen bulbs. The polycarbonate lens and resin housing are sonic welded to prevent moisture and corrosion. Includes a rubber mounting grommet 3-prong plug and instructions for easy installation.
