On the front or rear.

It depends on the length of the machine. Generally, only one light on each side is sufficient.

No, the light is only emitted to signal pedestrians and other vehicles.
To issue a warning to the operator/machine, it is necessary to purchase the ACR Anti-runover System.

What is the purpose of the ACR safety lights for forklifts?
Mark a safety area around the forklift to reduce accidents due to pedestrian runovers and collisions, especially at intersections.
We offer 3 different formats:
• Point: projects an intense beam of light on the ground in front or behind the vehicle, signaling its passage in advance;
• Arrow: in addition to signaling the passage, it also indicates the vehicle's movement;
• Line: delimits the area where pedestrians can approach. It should be installed on the vehicle's side, but can also be installed on the front or rear.
The 3 formats are available in blue and red.
