A completely dead car headlight is a serious problem that needs to be fixed immediately. Before that, you can check it personally to know the main cause of the issue. 

There are five steps to identify the faulty light component that can be done before taking it to the workshop. Let's check it out here!

1. Check Connections and Wiggle

One common condition is when the car light suddenly goes completely out. This can be fixed by yourself, so there’s no need to take it to the workshop. 

To do this, start the engine and the car lights, then check all connections. If there are no issues, it can be resolved by wiggling it.

If the light suddenly flickers on and off, it can be assumed that there are no broken connections. The cause of the light not turning on is likely due to a loose or dirty socket. 

You can clean it with contact cleaner, and make sure to clean the socket regularly to prolong the life of the light.

2. Ballast

The second step can focus on the ballast that functions to supply the power source, allowing the light to turn on. A sign of a faulty light component is indicated by dim or color-changing lights. 

If this condition occurs, you can change the position of the light to determine the condition of the ballast. After changing the position of the front light and it turns on in one of them, it means the ballast component is the problem. 

You can replace the ballast to restore its function. This way, car owners don’t need to replace the light or other components that can be quite costly.

3. Ground Cable

Did you know that the cause of the dead light is not only due to the light component itself? One common cause is a bad and dirty ground cable that needs to be cleaned. 

Additionally, the cable may be in an incorrect position, disrupting the performance of the light.

4. Fuse

You should check this component if both front lights of the car go out simultaneously. To identify the faulty light component, you can check the black box located near the steering wheel of this four-wheeled vehicle. 

This box serves as the electrical system for your car's front lights. The main cause that often occurs is a blown fuse, which prevents electricity from flowing and turning on the lights. 

You can check the condition of the light fuse to detect if there is a broken system or if it just needs to be replaced with a new component. This fuse can also deteriorate over time.

5. Bulb

After going through all the steps to check the dead car front light, but no issues are found, you can turn to the bulb, which is one of the main sources of this electrical system. 

One way to identify a faulty light component is from improper bulb installation or a bulb that needs to be replaced. The car's electrical system plays a very important role in illuminating the roads at night. 

This way, drivers are prevented from accidents or unwanted incidents. You can check the condition of this system with five easy steps before taking it to the workshop.
