Abstract

Emergency light system housing, with two replaceable covers is invented to supplement the prior art, U.S. Pat. No. 6,741,324 B1. The disadvantage of prior art is that it does not permit the cover of emergency light system housing to be replaceable. However, the present invention resolved this disadvantage by the way that it, creatively positions three connecting members on the cover and positions three holes on the housing. Three connecting members on the emergency light cover come to be respectively combined into three holes on the emergency light system housing. The shape of emergency light cover could be various as far as three connecting members on the emergency light cover are Properly positioned as described in the claim so that they come to be respectively combined into three holes on the emergency light system housing. The present invention could reduce an economic burden on an user because he or she could change only a different shape of emergency light cover with an existing cover without a need to change an entire emergency light system including housing with a circuit board and two covers with new one. In addition, the present invention is designed to shed a light in any direction by attaching the replaceable cover and the movable ball-shaped emergency light with a movable plastic circle. However, the movable emergency light is designed neither to be turned left or right side beyond 360 degree because of both one protruded-up and square-shaped object attached to the plastic moving circle and one blocking object located in the respective replaceable cover, nor to be turned downward or upwards beyond 80 degree because of both two protruded-up cross-shaped lines on each surface of two respective plastic ball-shaped covers and two respective smaller holes located in the movable plastic circle.
