Turn signals are a type of light device on vehicles

A turn signal is a lighting device on a vehicle that is used to indicate the direction in which the vehicle is turning, to help other vehicles and pedestrians understand the vehicle's driving intentions, and to increase safety on the road. Turn signals are usually located at the front and rear of the vehicle, and are used to indicate the left and right turns of the vehicle respectively.

When driving, when it is necessary to turn or change lanes, the driver needs to switch on the turn signals in advance to inform other drivers and pedestrians of his or her intention to drive. This allows other road users to react accordingly in advance to avoid traffic accidents. If a driver makes a sudden turn or lane change without switching on his turn signal, it will cause nuisance and danger to other road users.

A turn signal is sometimes referred to as a direction indicator or turn signal. They are usually connected to the steering wheel of the vehicle and automatically flash when the driver controls the steering through the steering wheel. Turn signals usually flash twice or three times a second, depending on the design of the vehicle.

In addition, in some newer vehicles, the turn signals are connected to the vehicle's intelligence system, allowing for more functionality. For example, some high-end vehicles are equipped with automatic turn signals, which automatically switch on when the vehicle is turning on the motorway to alert other vehicles. Others combine turn signals with the vehicle's speed and cornering to make the blinking frequency of the turn signals more in line with the needs of the turn.

Overall, turn signals are a very important safety device on vehicles that can improve traffic safety on the road. Drivers must be careful to switch on their turn signals in a timely manner to inform other road users of their driving intentions and avoid traffic accidents. At the same time, vehicle manufacturers should also continue to improve the design and function of turn signals to enhance the overall safety of vehicles. Only when everyone takes this small device seriously can we make the roads safer and smoother.
