What is bi-xenon in a car and how to connect it

How to install H4 bixenon with your own hands: schemes and connection sequence

It’s no secret that in the head optics with a single double halogen bulb, combining a dipped and a driving light, the usual monoxenon light source can not be installed. Bi-xenon bulbs with a corresponding three-pin H4 base are designed for such headlight categories.

What the lenses in automobile optics are for

It is not a secret for car owners that the regular lighting often fails to do the job, the headlights shine dimly, and the beam of light is dispersed and dazzles more oncoming traffic than shines on the road. It is especially difficult to light the way when entering curves, the lenses have a beam of light, it is more directed.

Lensed headlight is a separate round lamp in the form of a bulb, it has its own body, reflector and the lens itself. Such a design is built into the regular headlight, often the optics are equipped with an automatic corrector. But lenses from the factory are rarely used together with halogen bulbs, standard bulbs emit a lot of heat, because of this lens bulbs are strongly heated and deformed.

Selection of bi-xenon lenses and their price

When choosing lenses, you should take into account that they can be of two kinds:

1. Universal – put only in halogen bases, it is not necessary to interfere with the design of the headlight. Available with mounting size H.
2. Original – are installed directly at the factory when manufacturing the car. Bi-xenon can be replaced only by buying a similar size.

Universal lenses g5 3 inches.

Suitable for any car, very compact, so they are easy to install. Provide a wide dipped light, which begins as early as two meters from the hood. Cost from 3.5 thousand rubles.

The special structure allows you to quickly switch between low and high beam. Lens life reaches up to 3 thousand hours. The design includes metal curtain and focusing lens. The price is 3.4 thousand rubles.

What are bixenon lenses?

Bixenon lens (bilinx) is a set of optical elements installed in a car headlight. It usually consists of:

• xenon lamp;
• reflector;
• metal curtain;
• focusing lens;
• mounting elements.

Sometimes it may also include the ignition unit for the bulb.

The kit includes lenses, reflectors, xenon lamps, curtains and mounting elements

The principle of the lens is different in that the light emitted by the lamp is not just reflected by the reflector, and is formed into a beam by focusing. Switching modes “dipped / far” here is carried out by means of a movable metal curtain. When the dipped beam is on, it is in an elevated position, blocking part of the main stream. When you switch to “high” mode, it rises, opening the lamp completely.

The difference between halogen and xenon headlights

The fundamental difference between the installation process of Bixenon and Xenon lamps

For Bixenon lamps, the connection scheme is a little more complicated due to the presence of an additional high beam mode. Since the latter is activated not by igniting the second filament, but by moving the metal screen, the lamp control algorithm is slightly adjusted by additional wiring (On a side note: you can read about the connection features of Xenon lamps here).

In a more approximate format, the peculiarity of the circuit is as follows:

• “+” and “-” go to the ignition unit when the dipped beam is activated;
• When the high beam is activated, the “+” goes to the device that changes the focus of the light.

The connection can be made according to one of two scenarios, the choice of which predetermines the type of kit :

• with a relay per lamp or no electronic key;
• With one common relay for two lamps.

What are the bi-xenon headlights

Xenon lights are lights or headlamps in which special gas discharge lamps are installed, there is no incandescent spiral in them. Due to the design features of the lighting elements a directional beam of light is created, to improve the efficiency of the light flux xenon is used together with lenses. The main advantages of xenon headlights over halogen headlights:

• directional flow of light;
• economical power consumption;
• brighter illumination.

Directional light stream dazzles the oncoming drivers less, because it is directed on the road and is not scattered. Xenon lamps are mainly used for dipped beam, the bright beam is not always appropriate for long-range lighting. Bixenon is used as a combined light (the lamps switch to both high and low beam), the light flux is switched by a moving electrode inside the bulb. Also change the “far / dipped” can be made by installing a moving curtain or screen, often standard bixenon optics is equipped with automatic headlight control system.

Bixenon Benefits

Bi-xenon lenses have undeniable advantages over conventional headlights:

• provide a high level of visibility, while not blinding oncoming cars and people;
• long service life – more than 3 thousand hours;
• allows you to get both dipped and high beam – most of the lamps are equipped with “curtains”;
• Universal lenses are installed quite simply, it is not required to completely change the design of regular headlights;
• Allow you to safeguard traffic on the road, because improving visibility on the road.

The responsibility for the alteration of headlights

There is a false perception that “xenon” in Russia are prohibited. In fact, it is not. According to the Administrative Code of the Russian Federation, it is forbidden to drive vehicles with light devices, which do not meet the basic requirements of the Regulations on the eligibility of vehicles for use. In other words, modifying headlights designed to use incandescent or halogen, with the installation of xenon light sources, entails an administrative penalty. By the way, there are no penalties for it. Part 3 of clause 12.5 of the Administrative Offences Code for the similar offence provides for the penalty in the form of deprivation of the right to operate vehicles for the term from six up to twelve months with confiscation of light devices. So, it is worth thinking three times before engaging in tuning the lighting system of your car.

As you can see, installing lenses is quite a complicated and time-consuming process. But the effect of the lensed headlights will really surprise you. And as for legality, then it is up to you to decide whether to drive with the old headlights, tuning them, at the risk of being deprived of rights, or buy the factory lighting fixtures with the appropriate optics.

How to install H4 bixenon with your own hands: schemes and connection sequence

It’s no secret that in the head optics with a single double halogen bulb, combining a dipped and a driving light, the usual monoxenon light source can not be installed. Bi-xenon bulbs with a corresponding three-pin H4 base are designed for such headlight categories.

How to install bi-xenon instead of ordinary halogen bulbs H4 on your own hands

Including in the kit chain with individual relays

The mechanical part of the installation process of Bixenon lamps is simple and absolutely repeats the method of monoxenon assembly:

• form a hole in the headlight housing for the additional wiring;
• To install Bixenon lamp instead of regular halogen one;
• Fix the ignition units in the immediate vicinity of the headlights.

The first installation of bixenon H4 with their own hands often causes difficulties precisely in the organization of the connection scheme. The stand-alone set does not provide for the presence of common for the two lamps life support elements – therefore, the installation process can be carried out sequentially . According to this principle:

• connection and test of the lamp on one headlight are carried out;
• manipulate the wiring on the second headlamp;
• the final test.

Kit with an individual relay in its composition usually contains the following wiring elements :

• 2 ignition units;
• 2 relays;
• 2 wiring harnesses with soldered diodes;
• 2 lamps.

According to the connection diagram set bixenon with an individual relay, the method of operation is as follows:

• To the connector that comes from the lamp and is responsible for moving the screen, connect the wiring harness with a diode;
• To the output of the above-connected harness three-pin connector is connected to the original wiring block, previously connected directly to the H4 socket;
• the wiring harness is connected to the relay;
• electronic key is included in the network by fixing the plus terminal on the battery and the minus – on the mass;
• ballast (ignition unit) is connected to the relay;
• lamp power leads are connected to the lamp control unit terminals.

Switching in the kit circuit without relay devices

In kits without relays, the diode is cut directly into the three-pin power strip. The connection scheme is absolutely identical, except for the operations related to the electronic key: the ignition unit power connector goes directly from the connection to the OEM block.

A little about the purpose of the diode

After the installation and connection of bi-xenon H4 with his own hands often found the following problem: do not switch modes dipped / far, while the lamp lights up. The reason for this is that the screen is already in the high beam mode. In order to eliminate the defect the direction of permissible charge flow through the diode is changed by reversing its polarity.

In case of mismatch of contacts location and polarity of the connector for Bi-Xenon installation and pinout in the OEM block the situation is corrected individually:

• the position of the diode;
• between the connector control magnet, which moves the screen from low beam to high beam, and the block from the switch harness or power connector (in the absence of a relay) is inserted adapter that changes the polarity;
• contacts in the ignition unit power connector are reversed.

Scheme of bi-xenon connection with a common relay for two lamps

Having such a set, it is advisable to conduct the mechanical part of the installation process for both headlamps at once. Work with the electrics should be performed in full accordance with the drawings developed for this option.

Analyzing the wiring diagram of the kit bixenon, it is easy to identify the main element – the common relay. It is with him and should begin the procedure of electrification:

• fix the plus terminal on the battery;
• Connect three-pin connector to one of the regular pads power halogen lamps H4;
• coming from the relay supply pads in 12 V are connected to the appropriate connectors on the ignition unit.

The following procedures are performed in relation to each lamp:

• connecting the high voltage contacts coming from the ignition unit;
• connection of the connector for controlling the position of the screen, which is removed from the relay;
• securing the minus terminals, which ensure the closure of the shield magnet control circuit.

Briefly about the process of connecting bixenon

The complexity of the operation to install bixenon with H4 cap with their own hands is the correct organization of communication between the regular control lighting modes, relays, ignition units, dual-mode discharge lamps of high brightness. Supplied with Bixenon kits wiring allows you to quickly and correctly electrify the lamps.

There are two types of wiring:

• self-contained, where each lamp has its own power supply channel (can be with or without a relay);
• Combined – here one common relay is used, which “tied” the power supply system of each ballast and, accordingly, the lamp.

Most manufacturers adhere to a self-contained wiring scheme.

After the installation of any wiring, it is important to check the correct operation of the lighting system. The inability to switch lighting modes in stand-alone mode in stand-alone wiring is more often affected by the direction the diode passes the current.
