How to repair the car headlamps leak
Know the reasons for the water, that once the headlamps of water, we have a way to deal with, and if the headlamps are not the best trauma, but can be replaced by bulb seal or glue method to enhance the blocking effect To solve. If it is difficult to determine where it is leaking, you can use the following methods to test: choose dry weather, open the headlamps to dry the inside of the fog, and then turn off and turn off the lights, take water pipes in a suspected place to smoke, such as light bulb Cover. After a few minutes if the headlights appear fog, you can conclude that the bulb seat seal is not tight and cause leakage, otherwise only the headlight of the adhesive at the problem. It should be noted that in the glue when it is best to remove the entire headlamps, the lamp cover adhesive clean, air-dried after the glue, so that the glue is more reliable.
If you change the lamp, you will notice that the lamp mounting hole is the only channel that can enter the headlamp. If the cover or seal of the bulb is damaged, it is not impossible for the steam to enter the headlamp from here. Some people will say that the bulb seat in the hood below, there will be no rain shower to the top, how can enter through the bulb This is a good understanding of the headlamps will be issued when a lot of heat, the lamp inside the air heating, the pressure inside the slightly higher than the outside world. At this point, if a place there is a gap, this pressure will be released, the lamp in the air becomes thin, once the lights out after the temperature drop, the headlamp pressure will be lower than the outside world pressure, and then through the leak Take some air to make up the balance, if you happen to be just rain or wet weather, then the water vapor is easily pulled into the headlights. When the next time the headlamps, most of the air is squeezed out, and then inhaled some water vapor, so repeated, the water will accumulate more.
he rain was fine, the headlamps in the water mist like a layer of yarn like a blindfolded shade, light and shadow from the line of sight and reminiscent of the rain in the helpless, change the headlights it And slow, easily around the headlamps of thousands of dollars so easy to get. Whether it is luxury cars or mini cars, and now almost all use the whole sealed headlamps. Compared to the old-fashioned detachable headlamps, its sealing effect is superb, inside and outside the air is not in circulation, the air of water vapor, impurities are never allowed to enter, which ensures the lampshade and bulbs have a longer life. Since the seal so tight, that water steam is how to channel it? In addition to high-speed driving in the road raised small stone crushing shade and water, the water vapor can also be through two ways to break through the headlamp defense line. Headlamp light bulb and reflective lamp holder is generally made of plexiglass and plastic, and then through the bonding method to become one, and can not be dismantled. Some new cars will soon be found in the factory after the headlamps of water, mostly jelly smear uneven, adhesive loopholes. And some in the long sun exposure, the glue made hard deformation, there is a gap in the adhesive seam, but also make water can take advantage of the machine.
