A stretch of highway in Holland 500 metres long has been enhanced with glow in the dark road markings.
The paint used to mark the road uses a 'photo-luminising' powder that charges up in daylight and then gradually releases a green glow at night, meaning street lamps are no longer needed. The invention is the work of interactive artists Daan Roosegaarde and the Dutch civil engineering firm Heijimans.
If the initial tests prove successful an official launch is planned for later in April.
After spending the day absorbing sunlight the paint can glow for as long as eight hours in the dark.
Speaking about the project in 2013 Roosegaarde explained that it was part of a government drive to cut energy use by shutting down street lights.
He said, "The government is shutting down streetlights at night to save money, energy is becoming much more important than we could have imagined 50 years ago. This road is about safety and envisaging a more self-sustainable and more interactive world."
