License Plate Light Stainless Steel LED. Been looking for a nice license plate light for your favorite ride? It is highly polished stainless steel. Want something a little more custom than normal? Meet the Cadillac of license plate lights. It features 6 super bright white LEDs. It measures about 7/8" x 8 1/8" and has two 1/4" coarse thread screws that are spaced at 7 on center. Not coincidentally, the same spacing as modern license plates!
