This light bar is 20" long and is made of polished aluminum. The oval bar make for a nice change from all the round tubing light bars on the market today. The bar includes three chromed aluminum lights with 50 watt halogen lamps and two clamps. The spacing of the clamps is 8 1/2" center to center. The lights can be placed all forward or all back or two forward and one back or one forward and two back.
