Do LED message centres actually pay for themselves?

The variable is traffic count. An LED display in front of 18,000 vehicles a day is a different asset to one in front of 1,200.

Content discipline is the second factor. Displays refreshed weekly outperform displays set once and forgotten by a wide margin.

Energy cost is now negligible relative to the older lighting it replaces, and auto-dimming keeps night-time output within most municipal codes.

For high-traffic corridors we typically see the hardware justified within eighteen to thirty months of consistent use.
