These are the exact same Hella lenses we use in the Award Winning 7″ round LED headlight kits. These lenses conform to SAE/DOT standards for street and highway use. They are glass lenses and retain that original look, fit and function. They do not come with bulbs. The lenses accept a standard H4 style bulb.
