Dangerous tasks performed outdoors require the use of colored lights for safety. For tow trucks and service fleets, amber LED lights are commonly applied, which is widely accepted for visual warning applications.
Found on LED strobe lamps and LED light bars, it is permissible to purchase these types of emergency lights. However, because the luminaries are closely associated with certain safety standards and official fleets, the utilization of such light color for work safety is heavily regulated.
Tow Trucks and Service Fleets
Amber is considered to be an effective warning light, next to blue (mostly used for law enforcement and official government fleets). In the US, local legislation governs the application of LED work lights. For example, in New Jersey, service vehicles that are commercially registered are allowed to use flashing amber strobes (N.J.A.C. 13:24-4.1[a]2).
Moreover, snow removal, plowing and service vehicles for sanding operations may rely on amber fixtures for real-time warning, when engaged in the task.
In other parts of the world, amber LED lights are used more frequently. For instance, in Quebec, the local transportation authority allows vehicles going on extended trips to apply for a special permit for the application of rotating amber lamps. Furthermore, fleets that carry out refueling and street maintenance are encouraged to use the colored warning lights without special authorization.
Mainstream applications for amber LED lights are numerous. Most permissible uses for the light color involves automotive units. Vehicles used for leisure off-roading, such as ATVs and compact trucks, can use amber lights without needing to apply for a special permit.
Agricultural vessels, such as tractors, cultivators, loaders and wheeled irrigation systems, may also use the colored lights without risk of citations. In most cases, the equipment comes with the amber LED light installed.
Outside of work lighting applications, amber LED lights are revolutionizing skin therapy in the medical sector.
