Inform others in traffic that the vehicle is braking. to warn you when you slow down or stop stop/brake lights; red.

This color was not chosen at random. What is behind the red brake lights? more than one logical reason there is.

Red light has the longest wavelength in the electromagnetic spectrum.

long wavelengths, It spreads less in the atmosphere, making it easier to see from a distance under difficult conditions. As you can imagine, being able to see well in traffic situations such as fog is of great importance.

Also red light Because it has little energy It does not irritate the eyes, which is why red is used in safety signs.

Another reason has to do with our eye cells.

Our eyes have 3 types of cone cells and these are sensitive to different wavelengths (short: blue, medium: green, long: red). As we just mentioned, red light has long wavelengths. by red-sensitive cones in our eyes can be observed very well.

Our last reason is the effect of red on our psychology.

Red is a color that is subconsciously associated with danger and attracts attention. Dangerous situations such as blood and fire associated. Therefore, red stop/brake lights increase attention.

On the other hand, because red has a high stimulation level, it attracts more attention. It can both increase stress levels and speed up decision-making.

Now traffic lights are red You must have thought of it!
