Abstract: A method of hazard highlighting for drawing visual attention to the alignment of first and second members, the first member having a first plane working surface and a first working edge; the second member having a second plane working surface and a second working edge; the first and second working edges being separated by a working clearance; the first and second members being displaceable relative to one another wherein, in a first operating configuration, the first and second plane working surfaces lie in a common plane with the first and second working edges juxtaposed with the working clearances separated by a minimum distance; and, in a second configuration, the first and second plane working surfaces do not lie in the common plane and the first and second working edges are displaced from one another to a greater or lesser degree with the working edges being separated by a distance greater than minimum; the method including the step of projecting a light ray or pattern from a location associated with the
