Abstract
233,612. Murray, L. E. R. Nov. 20, 1924. Signs.-An etched indication on the back of a glass sheet 4 is illuminated by a lamp arranged in a socket at one or both of its upper corners. At the back of the glass 4 is a backing plate 7 of sheet metal bearing an indication in register with that on the plate. At the front of one of the sockets 9 may be a red disc 17. The other may display a yellow disc and, in the case of a rear number plate, the lamp in this socket may be switched on when required by the driver of the vehicle. The sign may be two-sided. The edges of the plate 4 may be silvered except at the corner or corners 6.
