How Reflective Signs Work

How Reflective Signs Work

29th Sep 2020

Reflective signs have made it easier for people to read signs when driving at night. This great invention

has changed the way we approach road safety. So, what is the science of reflective signs? How do they

work? Are there any reflective sign alternatives? We have the answers to these questions and much more.

How Are Reflective Signs Made?

Reflective signs can be made a few different ways, but most professional manufacturers use sheeting

made of either Engineer Grade glass beads, High Intensity lens or Diamond Grade Cubes. These create a

reflective sheeting that reflects the headlights of a car back to the driver, ensuring that the sign is

visible day and night.

Unfortunately, many cheaper manufacturers fail to use quality reflective materials like 3M or use weaker

or less reliable materials — such as .040” or .024” aluminum. With such inferior quality materials, the sign

will wear out after a year or two.

Are Reflective Signs Better Than Traditional


In some ways, reflective signs are superior to traditional signs. Since people started using them almost a

full century ago, they've saved countless lives. The added visibility has helped keep drivers, passengers,

and pedestrians safe, especially at night. For this reason, they're the preferred choice for many

communities that want to prevent accidents due to unclear signage.

Essentially, every sign is made more effective by reflective sheeting. For example, reflective street signs

make it easier for people to reach their destination when driving late at night. Reflective signs also

increase the visibility of urgent signs, including stop signs, railroad warning signs, speed warning signs,

and school zone signs.

Try Solar LED Signs

If you're looking for an alternative to reflective signs, you might want to consider solar LED signs. Highvisibility,

solar-powered, blinking LED signs are just as visible as reflective signs. You can even set up

timers to ensure that your LED signs only turn on when you want them to.

With reflective signs, however, they don't need to be charged, turned on, or put on a timer. Their reflective

sheeting makes them incredibly effective both day and night, so long as they come from a high-quality
