Common faults of xenon lamp

1. Problem: After installation, the light can be lit normally, but the fault alarm light on the instrument panel is lit.

Such as: Audi A4 1.8T, BMW 06, sagitar low beam, Magotan, Ming Rui, Fox, Volvo low beam, Peugeot 206, etc.

Principle: The original car is 50W-60W, and the xenon lamp is 35W. Some high-end European and American cars will detect "power mismatch" after computer testing, so the red light is on. Or the current does not circulate. Or the start-up radiation interference is large.

solution

1. The problem can be solved with a special wire group with resistance (25W), which is 25W+35 W, just 60 W, just like the original car, so the computer test is normal.

2. Add a decoder to balance and adjust the current, so that the starting current of the xenon lamp is consistent with the original halogen lamp.

3. Add anti-jamming devices.

Second, the problem: after installation, the computer board will be burned due to electromagnetic interference of the automobile circuit.

Such as: Buick LaCrosse, Buick Luzun, Modern Yuxiang Advanced Edition, Coolpad, Grand Cherokee.

Principle: The original car is equipped with a special electronic circuit board, which is easy to be disturbed and will burn out the circuit board or the lights will flash or go out automatically.

solution

1. It can be solved by special ballast with special configuration circuit structure.

2. Or install relay wire group.

Third, the problem: after installation, the light bulb flashes or often goes out or the left and right lights are not lit at the same time.

Such as: 06 BMW X5, 325 1, 520 1, Mercedes-Benz S350, S500, Land Rover, BMW Brilliance 3 Series, etc.

solution

1. Check whether the working current of headlight circuit is normal.

2. Add special flash and insufficient decoder.

3. Check whether the headlight circuit passes through the driving computer. If so, it needs a special decoder to recover.

Fourth, the problem: after installation, the low beam or high beam may be a little astigmatism (this phenomenon is common in ordinary telescopic lights, and the corner lights completely solve this problem).

For example: 1. The effect of Bora car is poor, so it is recommended to replace the assembly or the high and low lights dedicated to Bora with the manufacturer.

2. Modern Tucson must use special high and low lights with the shortest base.

3. The old GL8, Mitsubishi Lingshuai, Pajero, Swift and Bluebird all have astigmatism, so special H4 corner lights are needed.

Verb (abbreviation of verb) Problem: After some models are equipped with HID lights, there will be signal interference when turning on the radio.

Principle: Because the frequency signal in the ballast is incompatible with the frequency signal of the car radio, there is interference. At the same time, there are also directional reasons.

Solution:

Ballast can be installed by shifting or rotating direction, which can basically solve the problem. If the signal problem is completely solved, the ballast should be shielded and isolated.

6. Problem: Some models have installed HID lamps for a period of time, and the lamps cannot be dimmed. After inspection, the high beam fuse was blown, but it was broken after the fuse was changed and the light was turned on. What is the reason?

Principle: This is a short circuit phenomenon.

Solution:

First of all, it is necessary to check in detail whether the line is broken, short-circuited, whether the wiring is wound, whether the tape is ironed, and then test whether it will be short-circuited with a new ballast. Eliminate the above faults and replace the wire group to solve the problem.

7. Question: Why do the high beam lights of some models turn on or off after 10 minutes?

Principle: It is caused by insufficient starting current. The starting current of HID needs about 8.5A (it will stabilize to about 3.5A after one to two minutes), while the current of the headlight circuit of the original car is designed to be 5.5A-6.5A, so the starting current will be insufficient, so only one set of HID lamps can get enough starting current, so it will be turned on and off, which will happen in some high-end models.

Solution:

1. Add a relay circuit to supply power directly from the battery.

2. Check whether the contact between the 12V input end of the ballast and the socket is loose. This situation will lead to insufficient power supply of HID due to vibration when the vehicle is driving.

3.HID lamp belongs to high-pressure gas discharge lamp, and high-voltage protection circuit is added in ballast. In case of abnormal situation, the ballast will automatically cut off the power supply to ensure the use and vehicle safety. After the abnormal situation is eliminated, the ballast will work normally again. If the problem is not solved, you can mail the ballast back to our company to readjust and check the reason.

8. Question: After installing a set of H4 telescopic lights, they will expand and contract when turned on.

Principle: The reason is that the ground wire (negative electrode) is poorly grounded, the wire plug is poorly contacted or the power input plug is inserted backwards.

Solution:

Plug the plug backwards to solve the problem.

Problem: After Passat installed the HID lamp, the CD sound will stop when changing the lamp. What is the reason?

Principle: The reason is that the pulse frequency generated by HID xenon headlights when starting is the same as that of the original vehicle main engine, which leads to the original vehicle main engine receiving the wrong signal, thus making the sound stop.

Solution:

Passat original car circuit research and development special stabilizer, which can be installed and used with this product.

X. Question: Buick Excelle can't put the light bulb in this car because the lamp socket is too small. What is the solution?

Principle: The design of Buick Excelle and the original car assembly is a little small, so the light bulb can't be inserted.

Solution:

Just hit the cup with a hammer. (Note: Pull it out when you smash it, so as not to cause unnecessary trouble when the remaining powder falls into the lamp cup. )

XI。 Question: After Mazda M6 is equipped with HID lights, the far and near lights are all on, but they can't be dimmed. What is the reason?

Principle: This phenomenon belongs to circuit fault.

Solution:

First, check whether the headlight circuit of the original car is normal, whether the input power of the ballast is normal, and whether the fuse of the low beam on the line group or the original car is blown, and eliminate the above faults. It is possible that the low beam lamp plug was inserted wrong during installation, and another one can solve it.

Question: How to adjust the light level?

Solution:

Aim the front of the car at a wall at a distance of about 10 meter. Pay attention to the alignment without any deviation and keep your body level. In order to be as accurate as possible, you can draw a mark with chalk, paying attention to the normal load standard of the vehicle, that is, there is no extra load. Finally, debug:

1, turn on the light, and the light circle projected on the wall is the basis of correction. The distance between the center point of the two lamps and the front axle of the car should be equidistant from its projection on the wall, otherwise it should be adjusted according to the third step. The distance between the center point of the right lamp and the ground should be equidistant from its projection on the wall, and the distance between the left lamp and its projection should be higher than 10CM. .

2, adjust to a straight line, the left headlight must be absolutely straight ahead, and the right headlight can be slightly to the right, because you can see clearly on the right. It is valid in foggy days.

3. Cover a headlight for easy adjustment. Cover a headlight with a thick cloth, so that you can adjust effectively according to the change of the light beam emitted by a headlight on the wall. When debugging, use two screwdrivers, one to adjust the height of the beam and the other to adjust the width of the beam.
