If you want to know what Dial4Light is and aren’t clever enough to dissect the title I will fill you in. Dial4Light is probably the smartest idea I have heard in awhile. And I hear a lot of ideas.

Dial4Light is a service aimed at [cutting energy costs](https://www.trendhunter.com/trends/what-ai-can-save) in small and rural towns. Citizens of these towns have to [make a phone call](https://www.trendhunter.com/trends/dial-anyone) to Dial4Light if they want to ward off vampires/killers/scary people/darkness and turn the lights on.

So far Dial4Light has been saving money in the [small German towns](https://www.trendhunter.com/trends/intelligent-urban-infrastructure) that it has been installed in. For more info on Dial4Light read the excerpt below or follow the link.
