The Super Bright LEDs' Line of Round LED Truck/Trailer Lights, available in red, amber or white, meet DOT FMVSS 108 requirements for use as tail lights, parking lights, stop lights, reverse lights or turn signal lights. The illumination helps increase visibility while consuming 90 percent less energy than incandescent lamps, according to the company. A lifetime warranty protects against factory defects or malfunctions. A weatherproof housing and sonically sealed polycarbonate lens are built to withstand impact with road debris and exposure to wet conditions. The lights also have a rustproof stainless steel three-hole flange for flush mounting in a 4" hole. The LEDs operate within a wide 914.8V DC range and draw no more than 0.2 amps of power, which allows for multiple LED truck/trailer lights to be wired to the same circuit. These LED lights accept standard 3-pin plugs.
