Illuminated signs — backlit boxes for the wall and lit A-frames for the pavement, both running a printed face you swap yourself.
A light box lights a printed face; digital signage plays a file. The box costs less and needs no content person, but changing what it says means printing a new insert.
The weatherproof models can — outdoor light boxes and the A-frames are sealed and rated for rain. The slim indoor frames are not; each product page says which it is.
The frame opens — snap frames flip on all four edges, the boxes take a slide-in sheet. It is a two-minute job with no tools.
