Abstract
Abstract A lighting strip for illuminating domestic stairways at the stair riser and stair tread that is both safe and relatively inexpensive. The device provides a lighting strip for supplying low level lighting in staircases or the like having, a means for providing a low level regulated voltage output from an ac voltage supply, a plurality of light means, a housing means for receiving and holding the light means, and the housing means is adapted to be installed under the juncture of a stair riser and stair tread, and connector means connects the light means to the low level voltage output.
