Here is a look up the light’s skirt. These lights are called “Complex Reflector Optics Design,” whatever that means, and get the job done with computer-modeled lenses. With one LED array for the low beam and two LED arrays for the high beam, I was kind of skeptical until I saw them. But the lights feature military-spec, die-cast aluminum housings with clear non-yellowing polycarbonate lenses, and they will work on anything from 9 volts up to 33 volts. The electronics are all sealed right there behind the lens with epoxy and should never get even a little damp. The lights are covered by a 3-year limited warranty.
