Car headlight light standard, what to do if car headlights get into the water

There are two kinds of water ingress in car headlights, one is slight water ingress and the other is severe water ingress.

1.Slight ingress of water.

After the lights are turned on for a period of time, the fog will be discharged from the lamp through the ventilator with the hot air, which will not damage the headlights and electrical circuits.

2.Heavy water ingress.

The water inside the headlights is enough to keep fish. Disassemble it, open the lampshade, dry it, check whether there is any damage or possible leakage on the surface of the headlight, if you find abnormalities, it is recommended to replace the sealing strip and snorkel of the headlight back cover.

3.Precautions.

After the headlights get into the water, it is important not to bake the headlights, which can easily damage the headlights, because the headlights are made of plastic, and the extra heat can easily bake the lampshades, and most of this damage is irreparable.

Hello How to deal with water ingress in car headlights:

If it is caused by the temperature difference between the inside and outside, just turn on the lights for a while.

If the water ingress is caused by poor sealing, the headlamp needs to be disassembled, the lampshade should be opened and dried.

If there is a large amount of standing water, the internal parts should be inspected for breakage.

You can buy the lampshade of the same model online and go to the auto repair shop to replace it. The reason for water or white fog in the headlights is generally that the headlights are not tightly sealed, or that moisture enters through the drainage holes.

How do car headlights get water? Automotive headlight water ingress solution? Especially in rainy and snowy weather, it is easy to have water vapor in the headlights of cars.

And there is a lot of fog in the headlights of the car, which many driver friends have encountered. At this time, the headlights are like watery eyes, which makes people feel pity. What's going on?

How can you be so aggrieved? Is it the poor sealing of the headlamp that affects the water inside the headlamp, or is the lampshade damaged and the water vapor seeps into the inside of the headlamp?

Car headlights water ingress way sharing: reasons.

There are two reasons why headlight lampshades have moisture.

First of all, there is a snorkel on the back cover of the headlight, through which water vapor enters the headlight and attaches to the lampshade, especially in winter and during the rainy season, when the temperature difference is quite large. As for why such a snorkel is kept, as the name suggests, it is for ventilation In this way, friends don't have to worry very much. In most cases, after the headlights are turned on for a period of time, the water vapor will be exhausted through the exhaust pipe and out of the lamp, without causing any damage to the headlights and circuits.

Furthermore, if the sealing cover of the headlight does not drip well, it is easy for water vapor to enter, which may be due to the large temperature difference during the car wash, and rain or water enters. There is one more case. Your headlights have been replaced, but they are poorly sealed due to a technical issue with the technician.

But whatever the reason, if that's the case, water vapor doesn't evaporate easily, so we should do something about it.

Car headlight water ingress method sharing: treatment.

Most of the water vapor condensed by the fog inside the headlights is basically not much. After 15 minutes of turning on the headlights, the water vapor will evaporate and will not stay inside the headlights. However, the fogging of the headlights indicates that the headlights are not tightly sealed, and the headlights should be sealed immediately to avoid water ingress.

Due to rain, car washes, and snow, there is a lot of water accumulation in car headlights. At this time, there is not only extensive fog but also widespread water accumulation in the headlights of the car.

Water ingress into headlights is mostly due to sealing problems with the lampshade for two reasons.

1.The sealing strip on the back cover of the lampshade deteriorates, resulting in a decrease in elasticity, which in turn affects the poor sealing. In this case, only the sealing tape needs to be replaced.

The second is that there are cracks in the connection of the lampshade. If the car has not reached the warranty period and the cracks are not affected by external forces (such as impact, etc.). The small partner can negotiate with the 4S store to file a quality claim.

If the car is expired.

It is inevitable that the lampshade will be damaged by external forces, but because of this small injury, it is not worth replacing the headlights at your own expense. If the crack at the connection of the lampshade affects the water ingress of the headlamp, we can go to the headlamp modification shop, where most of them will basically provide corresponding services, and the damaged lampshade glass has the necessary repair difficulty, which is not comparable with considering that the auto parts city separately purchased a similar model of lampshade glass and disassembled and repaired the original lampshade. Even so, the ** required must be far less than the cost of replacing the components.

In addition, the car reminded friends that the water in the headlights needs to be treated immediately, otherwise it will affect the brightness and penetration of the lights, which will cause a bad relationship to the usual safe driving.

There is a lot of rain in the summer, especially the recent heavy rainfall, and many vehicles have experienced severe tests. Some owners have reported that their car's headlights were submerged after wading through water. Below, I will introduce the hazards and treatment methods of headlight water, I hope it will be helpful to the majority of car owners.

Danger of water ingress from headlights.

As far as the overall structure of the headlights is concerned, whether they are ordinary halogen headlights, xenon headlights or headlights with LED light clusters, they will be equipped with a snorkel. The function of the ventilation tube is to exhaust the heat of the headlights as much as possible, maintain the normal working temperature of the headlights, and ensure the stable and safe use of the headlights. If the car is wading in water, the external moisture will enter the inside of the headlight through the snorkel and attach to the lamp cover, which will affect the headlight brightness and even damage the headlight circuit.

1.Slight ingress of water.

Drivers don't have to worry too much about the slight water ingress into the headlights. After the light is on for a period of time, the mist will be discharged from the lamp with the hot air through the snorkel, which will basically not damage the headlight and circuit.

2.Take plenty of water.

If the headlights of the car are seriously waterlogged, we need to disassemble them first, open the lampshade, and check the surface of the headlights for damage or possible leakage. If any abnormalities are found, the editors recommend that the sealing strip and snorkel of the back cover of the headlights be replaced immediately to ensure the normal use of the headlights.

Things to look out for:

Do not bake the headlights after water has entered them. It is easy to damage the headlights by doing this, because the headlights are all plastic, and the excess heat can easily burn the lampshade, and most of this damage is impossible to repair the stove.

Millions of car purchase subsidies.

It is common for headlights to get water and fog, even if the lens has not been changed, this can happen with xenon lamps! There are usually the following ways to deal with the situation!

1) The original car has not been altered or has been hit, and the lamp that has entered the water needs to be filmed or disassembled by the oven to separate the headlight assembly and separate the transparent lampshade and the bottom shell. Clean up old snake glue! Seal it with imported snake glue from the new, to be even, and slowly press it with pressure forceps!

The problem is solved!

2) The original car is equipped with a xenon lamp separately, which is usually caused by the opening of the tail lamp cover and the poor sealing! Because the xenon lamp needs to be connected to the ballast! The ballast has a certain volume and can only be fixed on the outside of the headlight!

So the back cover should be dug holes! Bring the back cover and let the car dry in the sun or turn on its own headlights to dry! What to stick to the gap in the back cover!

Problem solved! 3) If the lens is installed in the later stage, this is usually a manual problem, or the snake glue is uneven! I open it from the new and clean it from the new! Be sure to put the snake glue evenly, and squeeze it evenly!

Some stubborn ones are still pried open, and they are locked with a staple like a stapler! The problem is solved!

3) Knocked over. Usually the transparent shell is cracked! After treating the water mist with the method of 2), paste a piece of transparent film with the kind of transparent film attached to the body! The problem is solved!

Water ingress into the headlights of automobiles not only forms a water mist on the lampshade, reduces the irradiation intensity of the lights, but also easily leads to the ablation of the bulb and the short circuit of the circuit when the lights are used. So what to do after the headlights get into the water?

The first type: the headlamp with the lampshade is easy to disassemble, and the headlight assembly only needs to be removed; Separate the lampshade from the housing and use a hair dryer to dry the moisture; Then install and restore the lampshade, use glass glue to seal the entire side seam, and install the bulb and plug-in.

The second type: the headlamp (sealed) with the lampshade is not easy to disassemble, and only the headlight assembly needs to be removed; Using a hand drill, drill holes in the very bottom of the headlight (2 to 3 mm drill bits); Drain the water inside the headlights and use a hair dryer to dry the excess water; The drilled holes and side seams are sealed with glass glue. Finally, install the bulb and connect the plug-in.

Thank you for your attention!

As far as the overall structure of the headlights is concerned, whether it is an ordinary halogen headlamp, a xenon headlight, or a headlight with an LED light cluster, there is a ventilation rubber tube on the back cover. At the moment when the headlights are lit and even when the headlights are in use, a lot of heat will be generated, and the function of the snorkel is to exhaust the heat as much as possible out of the headlights to maintain the normal working temperature of the headlights

According to the statistics, in the traffic accidents caused by driving at night, in fact, there is no shortage of headlights, lighting effects, and Bijia is one of the main causes of accidents. Water ingress into headlights is an important factor causing poor headlight lighting effect. Today I will introduce to you the causes and solutions of water ingress in the headlights.

Solution:1Don't worry too much about slight water ingress inside the light lamp.

After the light is on for a period of time, the mist will be discharged from the lamp with the hot air through the snorkel, which will basically not damage the headlight and circuit. 2.Serious water ingress: If the water ingress is serious, the water inside the headlights is enough to raise fish.

So the author dismantled the reed wheel, opened the lampshade to dry, and checked the surface of the headlamp and found no damage. If the car is also heavily flooded, the lampshade needs to be removed and the headlight surface will be checked for damage or possible leaks. If abnormalities are found, it is recommended to replace the sealing strip and snorkel of the headlight back cover.
