The smart highway project was conceived by designer Daan Roosegaarde to help guide drivers in the dark.
A 600-metre stretch of the N329 highway was upgraded with these glowing lines, that absorb light during the day and glows for eight hours at night.

"The Glowing Lines on The Smart Highway replace standard street lighting to reduce electrical energy consumption. To have the world's first glow-in-the-dark car on our road is a privilege and it mirrors goals that we want to achieve with our Smart Highway," Daan Roosegaarde said.

The spray-applied coating absorbs UV energy and other visible radiation during daylight hours and glows for between eight and ten hours when the sun goes down.

The glowing car paint is now available along with glow-in-the-dark car wraps from Nissan. The paint contains a solid, odourless Rare Earth Metal called Strontium Aluminate.
