Onion lights are called so because they are made in a shape resembling an Onion. The design of these fixtures has withstood the test of time, as in previous days these onion-shaped lanterns were used in lighthouses as well as in fishing vessels for supplying dim light on the water surface. In the 1800s these onion shaped lights were used also in whaling ships. Because of their broad use of glass a clear, consistent illumination can be provided. The metallic ring/cage is generally added for extra protection of these lights, and so as not to disturb the disbursement of light.
