New PIAA LP530 LED 3-1/2" driving lamps feature exclusive
reflector-facing LED bulbs and a geometrically-perfect reflector to
provide precise beam control and increased output compared with ordinary
halogen bulbs. The LED bulbs are much more durable than halogen bulbs,
provide more output and consume far less power. PIAA LP530 LED driving lamps have two 3-watt LED
bulbs per lamp, which draws 0.5 amps per light. The outside diameter of
the lens is 3½ inches.
