I purchased this meter with the intent of building a mad scientist or Frankensteins lab prop. As the picture shows the glass is broken and there is no needle for the measured voltage. ( the one needle with the round bit on it is just an indicator).
Step 1: Inspect and plan
Next Lights, The scale has some convenient mounting holes at the bottom, a perfect place to mount a board for the lights.
Step 2: An unexpected find
Mounted perf board with a couple screws and nuts to bottom of scale.
