LEDs were produced as early as the 1960s. It has been widely used in household appliances in the 1980s, such as audio volume indication and switch indication. In the 1990s, some new domestic automobile instruments also used LEDs, mainly for charging instructions, and later to display engine speed conditions. For example, a combination instrument produced in Xiangfan, Hubei, has a row of LEDs next to the odometer. When the driver steps on the accelerator, the LED lights will turn on from bottom to top, and when the accelerator is released, the LED lights will turn off from top to bottom, which is quite eye-catching and beautiful. In the mid-1990s, China used LEDs to make high-position brake lights and installed them on cars. Because LEDs light up fast, they can let drivers behind the car know the driving conditions of the vehicle ahead as soon as possible, and reduce the occurrence of rear-end collisions.
Teach you how to maintain LED car lights
Classification of LED car lights: Mainly divided into external lamps and internal lamps. Common lights are: headlights, turn signals, taillights, fog lights, rear lights and so on. The following describes the maintenance and use of each main lamp one by one.
Under normal circumstances, as long as it does not light up, it means that the bulb has burned out and must be replaced. But if it is not completely broken, it is just that the brightness is reduced, and the light is red and dim, and it must not be taken lightly, because this may be a precursor to failure, and the reduced lighting capacity is also a major hidden danger to safe driving.
There are several reasons for the decrease in brightness. *Usually, there is dirt on the astigmatism glass or mirror of the lamp. At this time, all you need to do is to remove the dirt with a flannel or lens paper. Another reason is that the charging capacity of the battery is reduced, and the brightness is not enough due to insufficient power. In this case, a new battery needs to be replaced. There is another possibility that the wire 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 bulb, but even causes the wire to pass through heat and cause a fire.
Various car lamp maintenance methods:
Generally speaking, friends who often drive at night should consider replacing a pair of higher-brightness headlights. In this way, in the dark night, enough brightness can help you see all the details of the road. Can let you see further. If the premise permits, you can even replace a pair of xenon headlights (hid). Xenon lamps not only have sufficient brightness and long life, but also have a feature: the color temperature is very high, and the color temperature close to daylight is also a kind of protection for the driver’s eyes.
Do not underestimate the taillights of the car. If the taillights fail, it is very easy to cause a rear-end collision. Generally speaking, as long as it is not a malfunction, there are not many options for upgrading the taillight. In addition to installing a transparent lamp housing to increase the viewing, it is a good choice to replace the traditional light bulb with an LED luminous body. Not only does the brightness of the LED increase, the response time is also faster Traditional light bulbs have been shortened, which means that when you step on the brake pedal, the LED brake lights can light up earlier than ordinary light bulbs, so that the trailing vehicle has more preparation time.
Fog lights are also commonly referred to as spotlights. As the name suggests, the main purpose of fog lights* is to ensure the driver’s sight in bad weather and to ensure that others can see you. Nowadays, many manufacturers install fog lights only to make the front bumper more beautiful. The quality of the fog lamps selected is relatively poor. Like the headlights, in addition to replacing fog lights with sufficient brightness, choosing a pair of hid xenon fog lights is also a good choice.
Reversing rear light:
Reversing in the dark is really a headache, especially for drivers with poor eyesight. The weak light of the original reversing lights is actually not much help. At this time, you need a reverse rear light. This is an independent lamp installed in the middle or under the rear bumper. It will automatically light up when you put down the reverse gear. Its strong brightness makes you reverse at night. Don’t worry about it anymore.
