The author has owned the X-Trail for nearly 3 years. Since most of the car use occurs during the day, the lights have not been changed. However, recently due to some reasons, the use of the car at night has increased. At this time, the X-Trail's halogen lamps are illuminated. The shortcoming of poor lighting effect became apparent, so lamp modification was also put on the agenda. It coincides with the May Day holiday, so if you have nothing to do, just "fiddle with" the headlights.
This is the original car headlight. The near and high beams are all halogen light sources, and there is no lens. The author has a 2017 X-Trail. Except for the top model, which has an LED light source, the other models use this halogen light, because the lighting effect at night is really good. It is not good and is called "candle light" by many car owners. If the car is used a lot at night, it is imperative to change the lights.
There are two mainstream types of light modifications, one is to replace LED headlights, and the other is to replace xenon headlights, and both need to install lenses. If you only replace the bulbs without adding lenses, the light will diverge and not condense, which will not only It affects your visual attention and also affects the view of the driver on the other side. Therefore, it is necessary to install additional lenses.
Between LED and xenon, the author believes that the safest way for Qijun is to install xenon bifocal lens headlights. Although LED headlights have lower power consumption, their penetrating power is not as good as xenon headlights, and in If it is turned on in rainy and foggy weather, it will reflect light, and the fog will reflect the light to your eyes. In addition, LED headlights have many advantages. For example, they turn on very quickly, while xenon headlights take about 3 seconds to turn on. Best lighting effect. After much deliberation, I could accept the 3 seconds, so I chose xenon bifocal lens headlights. Dismantling the bars, removing the center grille, and removing the lights were all done in one go. I chose Hella 5 from the Audi A6L for the xenon headlights.
Put the headlight in the oven to heat it first to increase its toughness and make it easier to disassemble. Also, the headlight needs to be heated again after it is modified. Someone may ask: What is a bifocal lens? This is easy to understand, that is, the low beam and high beam share a lens, and there is a light shield in the lens. Only a xenon bulb can switch between low and high beams by moving the light shield up and down.
Because the lens is very large and the light bulb socket of the original car is very small, it needs to be drilled with a concave round drill.
After drilling the holes and then installing it on the car, you need to install the lens below.
Of course, after adjusting the position, you still need to seal it, that is, seal the gap between the punched hole and the lens to make it waterproof and dustproof. The "square box" in the picture is a ballast. Its function is to instantly increase the 12V voltage to a high voltage of 23,000V, so that the bulb can achieve high-brightness illumination, and it can also increase the service life of the xenon lamp. The left and right headlights each have a ballast.
After adjusting the lighting point of the light to the appropriate position, the modification is basically completed. Because it was modified during the day, the lighting effect was not obvious.
This is the lighting effect after installation. In fact, the X-Trail's low beam and high beam are separated. A xenon bifocal lens can also be installed in another position. In this case, the light will be everywhere and the lighting effect will be more outstanding. However, I think a xenon bifocal lens Basically, you can get a qualitative improvement. Unless you are driving at night, there are many transport trucks and engineering vehicles with modified headlights on the road. Four lights can "compete" with them. Under normal use, one A xenon bifocal lens will suffice.
Compared with the yellow light emitted by the original car's "candle light", the xenon bifocal lens headlights emit white light, which is somewhat bluish and illuminates a longer distance. Especially in an empty underground parking lot, the night is as bright as day. . It is worth noting that when meeting cars, try not to turn on high beams, because the eyes of the driver on the other side will be "white" and you can't see anything.
This is the "perspective" of the driver on the other side. When I took the photo with my mobile phone, my eyes didn't recover for a long time and I was temporarily blinded. Therefore, high beam should be used with caution.
Overall, I am very satisfied with the effect of this lighting change.
