Abstract
A novel means for reducing the maintenance costs of cobra head lighting fixtures is presented, comprised of a new housing with a hinge at one end that allows the upper half of the housing to be lifted up for easy access to the lamp and ballast. There is a contact pressure switch in the enclosure which is opened electrically when the upper housing is lifted so that power to the entire enclosure is cut for the safety of the installer. The combination of the switch and the liftable upper housing reduces the steps necessary to do a bulb replacement.
