Inilah Fungsi Lampu Tanda Belok dan Rangkaiannya

The lights used for vehicles, especially cars, are not only headlights, but also turn signals. Turn signals, also known as indicator lights, have a vital function. In fact, all car drivers must understand the function of turn signals to avoid misuse. 

This light is also often referred to as a "riting." Generally, this light is located on the right side and at the back of the vehicle. Especially for cars, this light arrangement is very varied. 

Function of Turn Signals

Basically, every light installed is not only used for illumination but also to signal drivers behind and in front. Generally, this light is turned on when the car is about to turn left or right. 

The light blinks, making it easily recognizable. So, what functions do these turn signals have? Here are the details.

1. Turning Signal

The first function of this light is to indicate that the vehicle will turn or change direction, so other drivers will be informed. When about to turn, the driver should activate the light a few minutes before the turning point. 

Although it seems simple, turning on this light can reduce the risk of accidents on the road. 

2. Overtaking Signal

Another function it has is as a signal for overtaking vehicles in front. This signal will be received by the front driver through the rearview mirror. 

Not only for the front driver and vehicles coming from the opposite direction. But when overtaking, other vehicles will see the turn signal and can reduce their speed, creating space for you to pass.

3. Narrow Road Signal

One of the often-forgotten functions of turn signals is as a signal for oncoming drivers. Usually, this function is applied when on narrow roads. 

The aim is to inform drivers from the opposite direction so that they can exit the lane they are in when on a narrow road, allowing both oncoming drivers and you to get through. 

4. Lane Change Signal

If you often use toll roads that are identified by multiple lanes, turning on the turn signal is a must. This light should be activated when you want to change lanes. 

By turning on the turn signal, drivers behind your car will reduce their speed and can avoid accidents. Additionally, you will also have a smoother path when changing lanes.

Components of Turn Signals

In addition to knowing the functions, the components are also something that should not be overlooked. Here are the various components of this light, such as:

1. Battery

The first component is the battery. The battery serves as the source of electrical current. From this electrical current source, the entire electrical system can function. If the battery is damaged, the light cannot be turned on. 

2. Switch

Another component is the switch. The switch is used to activate the car's electrical system. Specifically for turn signals, the switch can be activated to the right and left alternately according to the desired direction. 

The switch is located not far from the steering wheel and has a lever shape. In this one lever, there is usually not only a switch used to turn on the turn signals but also the headlight switch. 

3. Fuse

Fuse or circuit breaker serves as a protector for the electrical circuit. The way this component works is by using a thin wire that has a current limit.

Given the importance of the function of turn signals, make sure you maintain them well. One way is to perform regular service at the official Daihatsu workshop. In the official workshop, the service will be performed by experienced mechanics. 

You can also book a vehicle service so you don't have to wait long for the service.
