In general, as long as it is not lit, it indicates that the bulb has been burned and must be replaced. But if it is not completely broken, but the brightness is reduced, the light is red and dim, and it must not be taken lightly. Since this may be a precursor to the failure, the reduced lighting ability is also a major hidden danger of safe driving.

There are several reasons for the decrease in brightness. The most common is that there is dust on the astigmatism glass or mirror of the luminaire. All you need to do is to remove the dirt with flannel or lens paper.

Another reason is that the battery charging capacity is reduced, and the power is insufficient to cause insufficient brightness, so that a new battery needs to be replaced.

Another possibility is that the line is aging or the wire is too thin, which causes the resistance to increase and affects the power supply. This situation not only affects the operation of the lamp, but also causes the line to overheat and cause a fire.

Various types of lights maintenance methods:

Headlights:

In general, friends who often drive night cars should consider replacing a pair of higher-intensity headlights, so that in the dark night, enough brightness can help you see all the details of the road, and when you hit the high beam, Can make you see farther. If the premise permits, you can even replace a pair of xenon headlights (hid). The xenon lamp is not only bright enough, but also has a long life. It also has a characteristic: the color temperature is very high, and the color temperature close to daylight is also a protection for the driver's eyes.

Rear light:

Do not underestimate the taillights. If the taillights are faulty, it is easy to cause a rear-end collision. Generally speaking, as long as it is not a fault, there are not many upgrade options for the taillights. In addition to installing a transparent lamp housing to increase the viewing performance, it is a good choice to replace the traditional bulb with an LED illuminator. The LED not only has increased brightness, but also has a response time. The traditional light bulb has been shortened, which means that when you step on the brake pedal, the LED brake light can be illuminated earlier than the normal light bulb, allowing the trailing vehicle to have more preparation time.

Fog light:

Fog lights, as the name suggests, the main purpose is to ensure the driver's sight in the harsh weather, and to ensure that others can see you, and now there are many manufacturers, the purpose of installing fog lamps is only to make the front bumper more beautiful, Therefore, the quality of the selected fog lamps is relatively poor. As with the headlights, in addition to replacing the fog lamps with sufficient brightness, it is also a good choice to choose an LED fog lamp.

Rear light:

Reversing the car in the dark is really a headache, especially for drivers who are not very good at sight. The faint light of the original reversing lights does not have much help. At this time, you need a rear light, which is an independent light fixture installed in the middle or below the rear bumper. It will automatically light up when you hang up the reverse gear. Its strong brightness makes you back up at night. No more worrying.
