The police beacon light is a convenient and economical safety device used on police cars. Like lightbars, they all serve as warnings. Due to the use of high-brightness LEDs, we can see the police beacon light from a distance, so that pedestrians and vehicles are aware that there are cars on duty coming.

Beacon light has many styles and colors to choose from, depending on the industry and the type of vehicle used.

For example, the most commonly used LED colors are red, blue, and amber.
In the United States, red police beacon lights are often used on fire trucks, so larger beacons are required; while in Europe, blue beacons are often used on police cars; of course, amber is the most used color, used for snowplows, Construction vehicles, construction vehicles and more.

The police beacon light is usually installed on the top of the vehicle, and the common installation methods are magnet installation and fixed installation. As we often see in movies, when the police need to be on duty, they will take out a beacon from the car. There are magnets at the bottom of the beacon, which can be easily attached to the car's roof. The beacon is usually powered by a cigarette lighter and connected by a spring wire.

In addition, the police beacon light generally has more than 10 kinds of flashing methods, such as 360-degree rotation or single flashing, double flashing, and triple flashing, which can be easily seen in bad weather or at night.

When purchasing a police beacon light, you must pay attention to the strength of the magnet at the bottom of the beacon. If the magnet is relatively poor, it is very easy to be blown off when the car is driving at high speed, causing safety problems.
