On the outside of my house I have a wall lantern that has a grounded convenience outlet on the bottom. I have seen bathroom fixtures with such an outlet but never an exterior fixture. The outlet does not have a weatherproof cover, and the outlet is only activated when the light is turned on. I do find the outlet convenient as I sometimes plug my shop vac into it to vacuum out the drain line for my central air.

Has anyone seen one of these? My house was built in 1976, but the builder seemed to often use old stock materials, so the fixture could be older. I don't understand how the manufacturer got away with not providing a cover for it.
