Not every car is staffed with good optics, which allows the driver to feel confident on the night road. Owners of inexpensive brands independently modify the headlights, making them more modern and vibrant. Lenses are great for these purposes. Moreover, the installation of lenses in the headlights is available to everyone.
About the design of automotive optics
The most popular way of tuning the headlights is the installation of bi-xenon lenses. They not only improve the brightness of the light, but also change the appearance of the car. On the example of an ordinary “Lanos”, consider this version of tuning.
This car for demonstration was chosen for good reason. The fact is that installing lenses is not possible in every optics, but only in those lights where there is no diffuser on the glass. For example, a standard headlight from a VAZ-2107 has special ribs on the reverse side, designed to scatter light so that it does not blind oncoming drivers. On most VAZ models, all lights are like that. You can try to put xenon lenses in the headlights on the "Lada" and "Samara", but the owner will have to buy other headlights. With standard optics, it will not be possible to achieve any effect.
The “Lanos”, unlike the VAZ, the headlights are made, like all modern foreign cars. They have a diffuser, but the central part of the glass is almost smooth. And this is not even glass at all, but a special plastic that is resistant to shock and elevated temperatures. Installing the lens in the headlights on such optics is possible.
Bi-xenon lens - what is it?
This is a set of parts that are installed in the standard headlights of the car. The kit includes a xenon lamp, reflector, metal shutter, focusable lens and mounting parts. Sometimes ignition blocks are also included in the kit.
The lens works as follows. The reflector not only reflects the light of the lamp, but also forms it by focusing into the beam. The high beam / low beam modes are switched by the curtain. If the driver turns on the low beam, the curtain is raised. It covers the main part of the light flux. When the motorist turns on the far, then the curtain rises completely. The lamp opens fully.
Headlight dismantling, disassembly
The car must be installed on a flat area. Next, remove the negative terminal from the battery. The headlights are fixed to the body with two bolts and a nut. They are turned away in turn. Then the optics should be gently pushed forward in the direction of the machine. All connectors from the case are disconnected.
A screwdriver unscrews the screws that secure the so-called "cilia". Next, turn the headlamp and remove the staples with a tool. Use a Phillips screwdriver to unscrew the screw - it is located on the back side.
Using a clerical knife, make a hole at the top of the cardboard box. The dismantled headlight is laid on the bottom. Then the box is closed, and the building hair dryer is pushed into the hole in it. Next, turn on the hair dryer for five to seven minutes. This is necessary to soften the sealant, on which the glass in the headlight is glued.
Then the optics are taken out of the box and carefully disassembled - you need to separate the glass from the headlamp housing. The mask will also detach with the glass. But she is not needed - she is left on the case. Unscrew the screw with a screwdriver, which secures the mask, remove the glass. Sealant will remain in the groove of the case - it is removed with a screwdriver.
Next, from the headlights, they pull out the insides that are not needed. This is a lamp, reflector, spring. Unscrew the screws with a screwdriver and remove the elements that are no longer needed. Then it is important to lay the wiring so that the chip can be brought out.
Reflector staining
Before you put the lenses in the headlights with your own hands, you will need to try them on. Some car owners also paint the reflector dark. So optics will acquire a more aggressive appearance, and decorative lighting will become more expressive in appearance. The reflector is no longer needed. To paint or not to paint it is everyone's personal business.
Before painting, the inner surface of the reflector is treated with a fine emery cloth - this is done so that the enamel lies as evenly and evenly as possible. Stained in two layers. After that, the part is dried a little.
Mounting Lenses
To install the lens in the headlights, it is recommended to wear gloves. This is to prevent the lenses from getting dirty with dust or other dirt. The mask or case is removed from the packaging. Also get an adapter made of silicone and a lens, which are inserted into the mask. Then they are screwed with complete screws. This design is mounted in the optics housing. On the reverse side, the assembly is screwed on with a contact nut. When replacing lenses in headlights, you can also use this instruction.
The decorative lighting ignition unit is glued to the optics housing on double-sided tape. Next, mount the lamp in the lens. All wiring is routed out of the chassis. Put a sealant in a special groove on the case, warm and glue the glass.
With poor-quality connection or depressurization of the glass docking with the lamp housing, the lens may sweat. This problem cannot be solved by replacing the lenses in the headlights. It is necessary to disassemble the optics and eliminate the cracks or re-glue the glass again. To clean the lens, it is recommended to use alcohol and soft lint-free fabrics. After cleaning the headlamps, it is better to blow off the inside of the housing with a compressor to remove dust.
Installation of ignition blocks
In the process of installing the lens in the headlights, one more issue needs to be resolved. A place should be found for the ignition blocks. Installation under the hood should be such that the devices do not interfere with the repair process. The best place is under the headlights. Drill holes in the mounting ribs, and the blocks are installed under them and secured with clamps. Then drill a hole for the “mass” for each of the headlights.
Mounting optics, check
So, when the lenses in the headlights with their own hands are already installed, it remains to be done only a few steps. The optics are fixed to their workplace, then secured with nuts and bolts. It remains to connect the wiring, replace the negative terminal on the battery, turn on the ignition and check the operation of a new light.
Adjustment
This is a mandatory step. The lenses in the xenon headlights after installation require adjustment - this is the only way to achieve efficiency from these devices and not blind the oncoming drivers. To set up you need a smooth vertical surface, tape measure and something to apply marking on the wall.
The car is put as close to the wall as possible. What is done next? On the surface of the wall draw a line that corresponds to the vertical axis of the machine. Then you need to move to a distance of 7.5 meters.
The tape measure the distance from the ground to the center of the lens. Next, measure the distance from the lens to the vertical axis of the machine. Then on the wall find a point that is located at the headlights level. Another horizontal line is drawn from this point at a distance of 3.5 centimeters down. Two lines are lowered on it perpendicularly - they should correspond to the centers of both lenses. The headlights are adjusted by the corrector so that the light beam is clearly at the intersection of the horizontal and vertical marks. This is how lenses are tuned into xenon headlights.
Conclusion
Here's how to make simple and inexpensive tuning optics. Properly installed and adjusted lenses will not blind oncoming drivers. And the car owner will get better visibility of the road in any conditions. With the help of instructions on how to put lenses in the headlights, even novice car owners will be able to do everything with their own hands.
