Just installed a set of Piaa 530 led driving lights I picked up on Amazon for about $200. Draw just 6 watts each, but put out very bright light. The led bulbs shine rearward toward the multireflector and the result is a precisely aimed beam that doesn't dazzle oncoming traffic like most led lights. Also have a 2-year warranty.
