My invention relates to‘ an illuminated number _ ends and with an‘ iron or similar bracket engag
or‘name plate of a type in which the light 'is re;
“?ectedl and‘either passes ‘through a stencil‘ hav
ing the numbers or letters thereon or is ob'‘ structed by opaque letters and numbers. In this
‘5‘ type of construction using re?ected light,a cer
ing‘ such lugs. By such ‘construction the: assembly
maybe positioned‘ on an. outside wall in a posi- _
tion to be illuminated by house lights or the
equivalent.

In the construction of Fig. 4 the molded prism
is made substantially in the same manner as de
scribed above, however in the assembly the glass
mirror 35 is omitted and the outer surface of
the inclined wall 43 is silvered or has a mirrored
surface indicated at 10. This mirrored surface
is thus on the outside of the transparent wall I3
and may have a protective coating outside of the
silvering or other metal used in forming the
mirror. It will thus be seen that so far as the
opaque ‘material and having cut-out or stencil
re?ecting qualities‘ are concerned, there is but lit
openings such as 4| de?ning the letter or
numeral. The upper or lower tabs 29 may be
