Different situations are for which you have to remove headlights from the car. Sometimes it is a simple tuning, sometimes due to damage. At first glance, it would seem that there is nothing difficult. Alas, there are many nuances that are very worth paying attention to. And so look under the hood and determine what we need and where to start. Initially, you need to decide which headlace we will change. It is mostly da type of headlights, factory headlights or tunned (Custom). Such headlights can be ordered from an authorized dealer, in special stores or on disassembly, if you are financially expensive to buy new ones. The most important thing that she approached your car. Let's consider the headlight device itself, so that before you remove it, what is responsible for. Despite the fact that the headlight is made, what manufacturer everyone has three main components, it is: reflector, diffuser and body.
Composite parts of headlights
Basically, the case is designed to store all the components of the headlights that are in it. Often it is made of plastic. Different lamps, halogen, xenon, or sometimes LEDs are used as light sources. The latter are gaining increasing popularity among drivers.
Variety of lamps for headlights
LED lamps are considered the most economical. Now they are fashionable to put them in all foreign cars and automakers, using such a case, translate everything to LEDs. They have a small size in size, which allows combining and make more complex light emitters from them. But alas there are also cons, the cost of such joy is very high, most often they are put only on premium cars or to the accessory to the car.
Next, consider xenon lamps. This is the main component of tunned headlights. In the process of work, they emit light with a bluish tint. For the first time they began to be used on the BMW 7 series. Then it was a luxury, and now this is no longer surprised. Manufacturers are still preferred to use classic halogen, but we will talk about them later. They are more efficient than halogen, somewhere three times, and the service life is much more and energy consumes less. Why don't make their manufacturers, the answer is simple, not in all countries they are permitted by law, and not all drivers are like. Yes, and the price of such headlights are fitting the cost of the car, plus the service is not cheap, do not forget about a number of harmful substances that are contained inside xenon.
As for the last species, these are halogen lamps, the most common and everywhere permitted by law. They are very easy to set up and in service they are not worth it. Both cost and in stores, they are quite acceptable. One is only difficult in the fact that a large amount of energy is consumed. It is based on the incandescent lamp. Also, the disadvantage is that it is not so easy to replace it, because halogen lamps are easily reacted with other substances. Replacing such a lamp to cost only for the base, in no case for the glass, otherwise it will immediately burn when it is first turned on. About the lamps everything that was possible was the most important, told.
We will examine on the spare parts of the headlight. In the design of the headlight, the reflector plays a reflector that forms a beam of directional light. The most simple reflector has a parabolic shape, but the basis of modern reflectors is laid more complex forms. Previously, they were made of metal on the principle of the mirror. Now replaced from plastic, as before to create a mirror surface, a thin aluminum film is applied and varnished is covered.
The third part is the diffuser, it skips the flow of light and, depending on its design, it can also refract the light. Another function is the protection of the headlights from external factors that constantly affect the headlight during the ride. It is often manufactured from transparent, dense plastic or glass.
Stages of removal headlights
Now proceed to the replacement of headlights. Often, specialists of technical centers do it very quickly and professionally. Usually begin with the fact that removing the radiator grille will thus, it will be much easier to reach the attachment and car bolts. In some cars it is necessary to sweat to remove it, BMW, Mercedes-Benz and Audi. For most models of these brands, the lattice opens with the hood. With the next step, we unscrew the bolts with which the headlights are attached to the car housing. Often in foreign cars they are fixed on both sides. Since the headlights are the first who takes on the blow of water, can take a little bit of the bolts, for this it will use anti-corrosion additives, I personally use the WD-40, ten minutes and how new are unscrewed.
It seems to be unscrewed all the bolts, now we will remove the headlight. There are brands of cars that do not need no effort to remove the headlight, unscrewed the bolts and it "fell out", and there are such where it will have to be counted, the bracket may be tightly to close, weather conditions are not the best friend of metal. In this case, we will substitute the fabric under the car body, so as not to spoil the paint and a piece of plastic or a screwdriver, in the extreme case, remove it from the edge. Now you can safely and slowly remove the headlight from the bracket, fastener for the headlight, then disconnect all the wires and lay them aside. When you understand that you can get confused on the wires, then make a photo in advance and then connect everything in the reverse order. By the way, do not forget about the security technique, before this remove the terminals from the battery, as it will be with us with an electronic part of the car. In principle, on this, the headlight ends, with similar manipulations, it is necessary to carry out similar manipulations.
Installing headlights
You can start installing new headlights, all actions are made in the same way, only in the reverse order. Connect the wires, install the headlamp to the bracket and fix the bolts back, the main thing is not to be excessive bolts, and the headlight falls on the road. Also do not forget that after reinstalling, the new headlights will need to adjust. Often I caught up on older. At the place where you will replace, turn on the old headlights and on the wall you need to note the extreme points where they are shine, and after installing new headlights, bring under the same parameters. The main thing is that the native headlights have been exposed in the right position.
