History of the headlight
The headlights of the headlights began to appear on serial cars in the 1960s. For example, the Chevrolet Chevelle, which appeared in 1966, could have ordered this option.
In the USSR, the first car with an omheer of the front optics became GAZ-14, more commonly known as "Chaika". Moreover, unlike foreign analogues, the flagship of the mining plant was equipped with this option by default.
In addition, not only headlamp wasers, but also headlamp cleaners were found in the VAZ 2106 and 2105 in the export version. Such vehicles were destined for the countries of Scandinavia and Canada.
But soon there was no interest in that option. As the practice showed, the faker of the headlights was suitable for shooting down the dust from the head optics. Serious contamination was not given to him. And it is not so dirty on the roads of Western Europe, so that the headlights become an indispensable tool for the driver. In addition, the consumption of the liquid liquid increased significantly, thereby permanently negating the merits of the liquid. Of course, on many cars, the washer maker was offered as an option, but was rarely ordered.
But in the countries of Scandinavia, the headlight washer, combined with the wiper brushes, turned out to be quite effective, especially in the winter. That's why I met in the cars of that time quite often.
The second life of the headlight washer was obtained by the active use of the xenon optics. According to EU standards, cars with gas-discharge light lamps must be equipped with a headlight washer.
Headlamp device and operating principle
The headlight washer is just like the windshield washer, just the difference that its nozzle is in front of the head optics. The tank of both omys, for the convenience of motorists, and in the year of the building of the subpotic space is common. The electrical pump may also be general or separate for each of the bleach. The headlamps of the lamp probe are often located above the sampling probe for the windscreen. This is done to ensure that only the windscreen is washed at a low level of the "non-freezing".
The headlamp washer generally does not have a separate power-on button. His work is combined with the work of the windshield washer. That is, when the driver includes a windshield washer, the same time the "non-freezing" is applied to the headlamps.
Advantage and disadvantages of the headlights
The main minus the headlight is the high consumption of the non-freezing liquid. Therefore, quite often, the motorists simply turn off the supply of liquid to the trout of the washer, prefering to wipe the headlights with a rag.
Many manufacturers are able to pick up the cars by the retracer headlights of the headlight. I mean, in a normal position, they're hidden in the bumper. And when the driver activates the headlight washer, the nozzle with the servo bar is moving from the bumper and applying the omits liquid to the headlights. But for the fans of the cold climate countries, this decision turned into a single headache. At low temperatures, the nozzle is often adjacent to the bumper and does not want to get out of the bumper or out. The force of the nook often went out of order. It is not surprising, therefore, that most car enthusiasts prefer to shut down the system.
Operation of the headlamps
Here, as with the windshield washer, you have to stick to several rules. First, in winter, only an unfreezing liquid should be used. Second of all, avoid getting dirt in the tank of the washer. Otherwise, the washer can be clogged. If it did, the cleaning should be done exactly as well as the windshield washer.
If your car is equipped with a xenon optics, and you decide to disable the headlight washer, it's better to give up this. The point is that light beam headlights dissipate and blind oncoming cars. In addition, according to the VSD, the washer washer on cars with the gas-discharge light optics must be made.
