What are the +sign found on most instruments Panels?
The + sign is the tapping/ and pressure point for engineers /crew which gives a good contact to complete the circuit in case the circuit opens or doesn't form proper contact during installation or flexing subjected to vibrations.

Because the panels do flex, subjected to vibration or during installation you are supposed to press in that area after installation to assure a firm seat, and yes you can press on that part if the gauge doesn't work or the backlighting goes out due to lose contact of the panel flexing.
In detail, the + marking is where the wiring loom/cannon plug/ earth connection is. Not just for the backlighting necessarily but sometimes the gauge itself.
