The illustrative embodiments described herein provide an apparatus and method for changing a display mode. The secondary amines are prepared by the addition of one or more primary amines with one or more male and fumar Michael receptors. The element may be braced outside said regions in order to further concentrate deformations within said regions. The glycerol-rich portion can be reacted with at least one of an oxidant and a catalyst at conditions sufficient to produce the partially oxidized reaction product. The head portion has at least one slot disposed therein that is adapted to receive an edge portion of the panel. A signal mirror includes a mirror and an LED lamp.
