Why unify the message
Status indicator lights only help if their meaning is shared. When every site uses the same color for the same state, users read any pile at a glance and panic drops accordingly, because a red light that means two different things at two sites is worse than no light at all.
Into daily work
Dongshang New Energy fixes one meaning per color, trains users on the signals, and audits signs so a burnt bulb or swapped label is corrected fast. Consistency is the product, not the decoration, and the cost of drift is paid in confused calls and a slow leak of user confidence.
The payoff
A unified language of lights turns uncertainty into calm. Users trust what they can interpret, and support calls fall because the answer was already glowing on the unit in front of them, so the simplest interface we build is often the one that prevents the most anxious phone calls from first-time users.
