German to English Tech/Engineering Mechanics / Mech Engineering

I'm translating a manual for a system for assembling products. In the description of the individual components, the document refers to a "Weitsichtstörmeldeanzeige" and a few other similar terms (e.g. Weitsichtmeldeleuchte).

These are simply displays or lights that are designed to be seen from a distance, i.e. across the shop floor. However, I'm struggling to come up with a neat solution for the "Weitsicht..." part in English. Unfortunately I need something short and snappy that will fit into tables and diagrams, so I can't really get away with paraphrasing it each time.
