Are the headlights high or low?
Headlights usually refer to high beams.
Headlights, also known as headlights, are lighting devices installed on both sides of the head of the car, mainly used for road lighting when driving at night. These lamps include a variety of types such as low light, high beam, daytime running lights, fog lights, warning lights and turn signals. Among them, headlights usually refer to high beam lamps, which are mainly used at night or when lighting is needed in fog, heavy rain, etc. The design of the high beam is mainly to provide stronger brightness and a wider lighting range, able to illuminate further and higher objects. In contrast, the design of the near-light lamp is for close-range lighting, the irradiation range is large but the irradiation distance is short, mainly used in urban roads or other situations where the lighting distance is short, to avoid too much interference to the car in front.
The headlight system of the vehicle also includes the switching function of the low light and the high light, according to the requirements of different driving conditions and traffic regulations, the driver needs to use the low light and the high light reasonably to ensure driving safety. For example, when driving on urban roads, low light should be used; In the case of no coming car on the highway, you can use the high beam. However, in the case of coming cars, in order to avoid interference with other drivers, it should be switched back to the low light in time.
What does headlight rain fog mode mean
The headlight rain fog mode is a special mode designed to improve the brightness of the internal light source of the vehicle headlights, effectively reduce the height of the headlight exposure, and disperse the headlight exposure range to provide better driving safety in the rain and fog weather. This mode achieves the effect of fog lighting by increasing the brightness of the LED light group, reducing its irradiation Angle and scattering irradiation range. After opening this mode, the brightness of the headlights will be brighter, and the irradiation range will be more dispersed, thereby improving driving safety. In addition, if you want to install fog lights, you do not need to register, because this belongs to the normal scope of motor vehicle modification, will not affect the use of motor vehicles. The lights and shapes of all motor vehicles will consume a certain amount of electricity in weather use, but will not have an impact on the use of motor vehicles. When the motor vehicle is in use, the generator generates electricity and charges the battery, so the amount of electricity used by the headlights is negligible.
What if there is water mist in the headlights
There are mainly the following ways to deal with water mist inside the headlights:
After opening the car headlights for a period of time, the fog will also be discharged to the headlights through the hot gas pipe, and this method will not cause damage to the headlights and the circuit.
If there is a high-pressure air gun, you can open the car headlights at the same time with a high-pressure air gun to the engine compartment is easy to accumulate a blow, speed up the air flow, take away water.
Car headlight desiccant can effectively solve the problem of car headlight fog, first open the back cover of the car headlight, put the desiccant packet into it and then close the back cover to ensure a sealed environment, usually four to six months to replace once.
Stay in the sun for a few hours and use the sun's temperature to vaporize the water mist.
Remove the dust cover of the headlamp, so that the water vapor inside the lamp can be quickly discharged, and can be dried with a hair dryer.
Check whether the surface of the lamp is damaged, it may leak, if there is damage, it is necessary to immediately go to the after-sales repair shop or the car 4S shop to replace.
It is not always abnormal that there is water mist in the headlights, especially under the right conditions, such as when the vehicle is driving in rainy days, the temperature inside the glass lampshade rises due to the light bulb, and the water droplets vaporize; The temperature on the other side is sharply cooled due to rain erosion, and the water vapor contained in the air will condense and adhere to the glass lampshade, that is, the car lights condense into fog. If the fog does not disperse, then there may be a problem with the lampshade and gasket, which needs to be investigated and treated with the above method.
