Road Stripes Glow at Night: The Simple Science Behind This Safety Feature

• White road stripes glow at night due to 'Thermoplastic Road Marking Paint' mixed with 'Glass Beads', not batteries or lights.
• The 'Glass Beads' cause 'Retro-reflection', sending vehicle headlight beams directly back to the driver's eyes.
• During the day, intense and scattered sunlight overshadows the retro-reflection, making the stripes appear as plain paint.
• Rain can hinder the glow as water on the glass beads obstructs light reflection, though advanced technology is addressing this.
• Road safety features like these stripes and "cat eyes" utilize simple reflection principles to prevent accidents.

Why It Matters: Road stripes use glass beads and retro-reflection for night visibility, enhancing safety without electricity.
