A trial of glow-in-the-dark (GITD) road markings on a section of highway in The Netherlands has been put on hold, after rain lessened the effect of the new lines.
The glowing lines have proven to be sensitive to large amounts of moisture which make them appear dull, and authorities have chosen to abandon the trial until the northern summer.
The trial had been running for around four weeks, with a section of the N329 highway 100km south-east of Amsterdam being the first to get the glowing lines.
Motorists were reportedly driving without headlights during the early stages of the trial to sample the new GITD experience, before rain began to reveal the line's weaknesses.
Dutch authorities will ‘fade out’ the current lines in an effort to avoid driver confusion while a solution to the moisture problem is sought.
"As expected the 'real life' trial enables us to learn from the environment and users,” civil engineering firm and trial conductors, Heijmans, said in a statement.
"We will use these insights to introduce an update to the glowing lines [but] in the meantime we have temporarily faded out the lining to prevent any confusing situations for road users. We are working on developing Glowing Lines version 2.0, which will be ready for this summer. It will then be introduced on a larger scale in the Netherlands and abroad."
It is unclear at this stage exactly which countries outside The Netherlands will experience GITD Lines version 2.0, but several are said to be watching the Dutch trial, including the UK.
When functional, the GITD lines are designed to offer a viable alternative to street lights on rural roads, and can glow for up to ten hours between doses of sunlight.
