GlowLine is a self-charging, solar-powered smart road marker designed to enhance nighttime road visibility and driver safety, especially in rural or poorly lit areas. Each unit combines energy-efficient LEDs or glow-in-the-dark materials with small solar panels, storing sunlight during the day to power light at night. Optional smart sensors can detect vehicles, weather conditions, or traffic flow, enabling dynamic lighting or data collection. This low-cost, eco-friendly system reduces accident risks, requires no grid electricity, and supports several UN Sustainable Development Goals, including clean energy, sustainable infrastructure, and road safety. GlowLine offers a scalable, innovative solution for safer, smarter roads.
