What is the purpose of highway laser lights?

[ElliottLee]

Highway laser lights serve as alerting and warning devices. These green lasers are anti-fatigue driving warning lights installed on highways, featuring high brightness and long range. They effectively stimulate the brain of drivers who have been driving for extended periods at night, helping to combat fatigue. The green laser beams on highways have a long projection distance and are particularly noticeable at night. The laser lights come in two modes: continuous illumination and strobe, with a range of up to 2 kilometers. These lasers are typically installed only on relatively straight sections of the road. The green laser lights create a crisscrossing network of beams in the air above the oncoming traffic direction, without obstructing the driver's view. Together with flashing lights and high-decibel alarms, they form a tripartite warning system combining visual, auditory, and light effects, stimulating the driver's senses and enhancing road safety awareness. Their effectiveness is especially pronounced during nighttime, rain, snow, fog, and other adverse weather conditions.
