Headlights of the common faults and causes
Auto lamps, especially the most prominent headlamps, in use for some time, due to the different environments and conditions Use, resulting in varying degrees of aging, which will not only affect the appearance of the vehicle, but also seriously affect the lamp illumination. As driving lights, in nighttime lighting only tools, its function is weakened, it will directly affect the drivers accurate judgments under the night-time road conditions, to a certain extent, increase the risk of traffic accidents.
Inside the car headlights fog
It should be noted that, even if the original headlamp, and sometimes there will be fog appears. This may be a small amount of moist air from the condensation to the inside of the headlamp the cooling channels in the walls of the chimney, due to the temperature difference.
Just open about 10 minutes of light, the fog disappears, it is a normal phenomenon.
But often a lot of fog, and even drops of water, and can not use lights to eliminate think, some drivers have met a lot of people will ask is not sealed headlights and headlight water inside? Or the lampshade damage, within the water vapor permeability headlights?
The headlights overall structure, whether ordinary halogen headlights, Xenon headlights, headlight and LED lanterns have a ventilation
Back cover position on the rubber tube. Currently, the LED is lit, and the use will produce a lot of heat, the role of vent tube, heat is possible discharge headlamps, in order to maintain its normal operating temperature, to ensure its stability.With moisture in the air will enter the headlamp through the breather tube and is connected to the lampshade collection drops.The gathered water vapor flow down the shade down. Most of these cases are caused by the large temperature difference, with multiple seasons of winter and rain most prone to this phenomenon.
In addition to changes in the weather, human factors also may cause the lamp to become one of the "tearful", such as vehicles wading, car wash. Wading of the vehicle, due to the engine and exhaust system, heat, rain, poured on top is relatively large, the large amount of steam is formed, and the exhaust pipe, the part of the water vapor into the interior of the headlamp. Decrease in the brightness of the headlights
The headlights and taillights, as long as it is not lit, it is likely the bulb burns out, the need to replace. However, if no Completely broken, but the brightness decreased, red, yellow, dim, and can not be taken lightly, because it has caused the failure.Decrease brightness for the following reasons: first, the low operating voltage of the light source. Luminous intensity light source, luminous flux, its operating voltage and life are closely related. May be dropped the charge capacity of the battery, so that the brightness is not enough, therefore, if you need to replace a new battery. Another possibility is that the impact of aging, or the wire is too small, resulting in resistance to increase the supply.
Second, the dirt on the the accumulated lamp of astigmatism glass or mirror. Then need to do is remove the dirt with a cloth or lens paper to clean.
3, light source aging or poor product quality. Long-term use will gradually aging, the luminous efficiency of the light source and the light emitting.Strength declined significantly, which should be replaced. More fake and shoddy products in the light source on the market, most products are not the regular manufacturers, so the quality is poor, you should use a good quality brand, so when purchasing a light source products.
