What is the purpose of the laser lights on highways?

[Eugene]

Warning function. The green laser lights can prevent fatigue driving with their high brightness and long range. For drivers who drive for long periods at night, they effectively stimulate the brain to stay alert. Additional information is as follows: 1. Highways have fewer reference objects due to their flat and straight roads, leading to monotonous driving actions that can easily cause drowsiness, especially in summer. Green laser lights are set up to stimulate the senses through light. 2. After multiple inspections, traffic police have placed these lights in areas prone to fatigue driving, typically on relatively straight road sections. The brightness is adjusted to an appropriate level to create a visual impact without affecting the driver's vision. Laser lights come in two forms: constant-on and strobe. 3. In addition to laser lights, there are also flashing lights and reflective strips that serve anti-fatigue purposes, enhancing drivers' awareness and ensuring sufficient rest time to prevent traffic accidents.
