These are superb reproductions of the famous Lucas Le Mans headlamps of the 1950's. They were designed for high-speed 24-hour races and were used on many rally cars, as they give far more light output than a normal sealed beam lamp. These are brand new in the box, with new tungsten BPF (British prefocus) bulbs. They will work with just about any twin 7-inch headlamp application, and they look terrific.
Halogen bulbs (12V 65/55W) are available for an additional $26.
