Years ago I made an illuminated house number. I soldered hundreds of
little LEDs across busbars. I might have posted pictures here at the
time. Anyway I decided I want an illuminated number on the new postbox
(made necessary by the gate), but this time I would take advantage of
the availability of LED panels. I used a 300 x 300 one because I
couldn't find a smaller square one. I cut the number out of an aluminium
panel (the side panel of an old PC). I tried to get someone to cut it
out with a laser machine but only one replied and they wanted stupid
money so I did it with a Dremel. It's a bit rough but no-one will
notice. The aluminium is fixed to a sheet of 2mm white perspex. The
whole thing will be behind a clear perspex window.

If your 2mm perspex is matted & touching the ali you'll get soft edges to the numbers & minor errors will become unnoticeable.
