How does it do that?

How will people notice the device?

Informational signs, bearing the IceAlert® symbol which states, “BLUE REFLECTORS INDICATE FREEZING TEMPERATURE” are placed at property entrances.  In addition, each IceAlerts® pedestrian unit is mounted on a 7″ x 10″ sign which states graphically “BLUE STAR=FREEZING”

Where do I place the IceAlert® devices?


Why do people need IceAlert® to tell them when it's cold?

People can feel the cold, but it is difficult to tell how cold it is. IceAlert® gives a very prominent blue reflective star when people need the additional information, only where the temperature is near freezing or below.

How does this help my customers or employees?


What is the life expectancy of the IceAlert® device?

We warranty our product for two years. We have customers that have used our product for ten years.

How long after I order can I expect to receive shipment?

Does direct sunlight affect them?

Yes, direct sunlight and the ambient heat from the sun can affect the reading of an IceAlert. If your problem area is in the shade, make sure the IceAlert is positioned in the shade to get a proper reading.

Blue Star System for Roadways

How does it do that?

How will drivers notice this system?

The BlueStar System™ symbol is in motorists “cone of vision” (see next FAQ)

What is the "cone of vision"?


Why should we invest in the Bluestar System™?

The Bluestar Roadway System™ can reduce the number and severity of accidents by changing drivers’ behavior.

How does it change drivers' behavior?

By giving them real time temperature information that can reflect temperature changes. Compare this to a sign that states, “watch for ice” that is there year round.

What do you mean "real time"?


How does it do that?

IceAlert® reflectors work as standard white reflective delineators until the temperature approaches the freezing point. Then they turn progressively blue between 38° and 32° F. They are site specific and continuous.

What does site specific and continuous mean?


Will the motorists understand this system?


How difficult is it to install and maintain?


How long will the reflectors last?

IceAlert® reflectors are very strong and reliable. Made of sealed injection-molded medical-grade poly-carbonate, they are able to withstand repeated and severe shocks to their face. They will provide years of information to your drivers.
