A pilot on a dark two-lane road<\/h2>\n\n\n\n
The test began on an unlit road in Hulu Langat, where drivers rely on headlights<\/a> and whatever the paint can reflect back. Officials described a pilot covering about 804 feet (245 meters) of roadway, with roughly 1,608 feet (490 meters) of photoluminescent markings applied as an alternative to raised reflectors known as \u201ccats\u2019 eyes.\u201d <\/p>\n\n\n\n In daylight, it looked ordinary \u2013 then it glowed at night.<\/p>\n\n\n\n Malaysia\u2019s public broadcaster RTM reported the project as a Public Works Department pilot meant to make dark roads easier to navigate. <\/p>\n\n\n\n Works Minister Alexander Nanta Linggi said the markings were more visible in the dark and could help road users feel \u201csafer and more comfortable\u201d on roads without streetlights. But even then, officials stressed they were still evaluating the pilot because it involved high costs.<\/p>\n\n\n\n The cost gap was not subtle. The minister said the photoluminescent paint cost RM749 per square meter, while conventional road marking paint was RM40 per square meter. <\/p>\n\n\n\n Using the 2024 average exchange rate (about $0.22 per Malaysian ringgit), that is roughly $15.20 per square foot for the glow paint, compared with about $0.81 per square foot for standard markings.<\/p>\n\n\n\n That makes the \u201cglow\u201d option about 19 times more expensive before you even get to how often it would need cleaning and repainting. If you have ever watched a road crew repaint faded lines after a rainy season, you already know why that matters. A pilot can look great and still be hard to scale.<\/p>\n\n\n\n In February 2024, Selangor officials said they wanted to expand glow-in-the-dark markings to 15 additional sites across all nine districts. The plan was to cover about 9.3 miles (15 kilometers) of roads without streetlights at an estimated cost of RM900,000, or about $197,000.<\/p>\n\n\n\n At the same time, Selangor\u2019s \u201cSelangor Bercahaya\u201d effort was also rolling out conventional LED streetlights, including 600 lamps already installed in its first phase. The state also said it had set aside RM150 million, roughly $33 million, for more LED street lighting. <\/p>\n\n\n\n That split strategy hints at a key point: glow paint was never the only path to safer nights.<\/p>\n\n\n\n By November 2024, the national tone shifted. Maslan told Malaysia\u2019s Dewan Rakyat that the \u201cglow-in-the-dark\u201d trial did not satisfy the ministry\u2019s expert group and the cost was too high, so they likely would not continue. He also pointed to a simpler fix: repainting and maintaining standard white road lines so they stay visible at night.<\/p>\n\n\n\n This is not the same as saying the markings never worked. It is more like saying they failed the full cost and performance test. For public infrastructure, that is often the final exam.<\/p>\n\n\n\n The dream behind glowing markings is simple. If the road can guide you without powered lights, maybe towns can trim their electric bill and reduce emissions<\/a> at the same time. Public street and area lighting can account for up to 40% of the electricity consumed by municipalities worldwide, so it is easy to see why a \u201cno electricity\u201d idea gets attention.<\/p>\n\n\n\n But most places cannot treat road lighting as optional, especially around intersections, crossings, and busy pedestrian areas. <\/p>\n\n\n\n The U.S. Department of Energy<\/a> notes that LED roadway lighting can achieve required light levels with less than half of the total generated light compared to older technologies, because LEDs can aim light more precisely. In practical terms, a lot of climate impact may come from straightforward LED retrofits and smarter controls, not only from experimental coatings.<\/p>\n\n\n\n There is another lesson here that applies far beyond Malaysia. The U.S. Federal Highway Administration says adequately maintained retroreflective pavement markings improve nighttime visibility and reduce crash risk<\/a> by reflecting headlight beams back toward drivers. <\/p>\n\n\n\n It also warns that retroreflectivity deteriorates relatively quickly, so agencies need active maintenance.<\/p>\n\n\n\nRead More: The National Weather Service Buffalo on high alert: Lake Ontario’s snow machine kicks into gear and threatens to paralyze roads with up to 3 inches of snow per hour<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n
