Read With Data
Indicator meaning should come from the documented spec, not from a veteran's hunch. A light that means one thing to one person and another to the next causes errors. Anchor meaning in recorded fact, and the reading stops depending on who happens to be standing there.
Skip The Extremes
Users either trust every light blindly or ignore all of them. Neither serves safety. Treat a signal as a prompt to verify, not a verdict, and escalation stays proportionate to the actual risk rather than to the user's mood that morning.
Own The Meaning
Dongshang New Energy names who maintains the indicator legend and updates it, so the lights stay a shared language rather than a private one that drifts between sites and confuses the next person to read it after a transfer.
A light with no owner is a rumour with a bulb. Name the keeper of its meaning, update the legend, and the indicator becomes a fact everyone reads the same way, which is the entire point of having one.
