These glow-in-the-dark road markings aren’t just pretty — they save money and energy, too.
These luminescent strips replaced streetlights on a 0.3-mile stretch of highway in the Netherlands, part of an experiment that might change the way roads are illuminated across the globe.
The roads markings, which went into effect Sunday night, might even one day be able to include temperature-sensitive paint to warn drivers of the possibility of ice.
The lights are charged up by the sun throughout the day and then last up to eight hours — long enough to get through most of or all the way through the night. But the real test is whether the paint can stand up to the wear and tear of constant traffic.

The team developed a photo-luminescent powder that, when mixed with road paint, can glow in the dark for up to 10 hours after charging up from the daytime sunlight. The paint was placed on a 0.3-mile stretch of highway N329, about 62 miles southeast of Amsterdam in the city of Oss. Studio Roosegaarde also aimed to add glowing weather symbols that would activate when the symbol’s corresponding weather conditions took place; for example, snowflake glyphs would appear on the road to indicate that the road is slippery and caution is advised. However, for now, only the glowing street lines have been implemented.
The Sunday Telegraph reported that, back in 2011, England’s Highway Agency shut off a significant amount of the country’s streetlights overnight in order to meet a carbon emissions goal. The mass turn-off ended up saving the agency about $668,000 (or £400,000). Another of the country’s councils estimated that setting one-third of England’s streetlights to either turn off during a certain period of time, or allowing them to be dimmed, would save around $1,337,000 (or £800,000) per year.
Anyone who had their own room in middle school knows from the staggering amount of glowing stars they pasted onto their ceiling that glow-in-the-dark fixtures don’t illuminate their surroundings. They light up themselves, but nothing around it. However, Roosegaarde said the team managed to get the paint to glow so bright that it seems radioactive — definitely a better level of brightness than the glowing stars you stuck to your ceiling fan before your first sleepover.
The team wants to take the glowing paint further, but so far they have not received new contracts. The paint has not yet been thoroughly tested by the rigors of time, so perhaps we’ll begin to see eerily glowing roads popping up around the world once the paint has shown to last through weather and time.
