Bicycle Lamp #76.846
"Fire Ball" nickel plated brass bicycle lamp, 10 cm. high and 7.5 cm. in diameter, exclusive of the projecting lenses. Top is hinged to permit filling the internal oil reservoir. Unfortunately, the mounting bracket is missing. The lamp has a clear faceted lens, 4 cm. in diameter, at the front; a 2.5 cm. diameter lens at the rear, and 2 cm. diameter green lenses on each side.
The lamp was manufactured by The Cycle Danger Signal Co., 107 Chamber St., New York City, who were in business from 1851 to about 1900.
These lamps appear to be quite rare; complete units have commanded high prices at auction.
