PCE reflex headlights feature a diamond-style lens that diffuses light in a prismatic beam. They include H4 12V 55/60 watt halogen bulbs and clear glass lenses. The result is a beam that's 60% brighter than your factory sealed beam lights, while remaining street legal, perfect for vintage vehicles and street rods. They're also much more durable, so they're great for off-roaders and work vehicles, too.
