Three ways to upgrade car lights

1. Install xenon lamp directly

Advantages: easy to install, corresponding to the original halogen bulb, choose the xenon lamp model, (most of the low beams of the European cars are H7, the high beam is H1, the low beam of Japanese cars is 9006, the high beam is 9005, and the light bowls of the far and near beams are all H4 Model): The price is cheap, usually around a few hundred yuan. There are various domestic brands of different brands. At present, the more powerful combination is the Shelllight bulb + Seablue star ballast.

Disadvantages: Since the production of xenon lamps cannot take into account the design of the reflector of each car, the focus is bound to be inaccurate, so that the light diverges, even the low beam will affect the opposite driving, which is an unethical modification.

The color of xenon lamp is determined by color temperature. 3000K is golden light, commonly known as golden eye, which has strong penetrating power, but it is easy to be visually fatigued when driving for a long time. 4300K is the original factory color temperature with better overall performance; 6000K is full white light, similar For the color of fluorescent lamp, the human eye looks comfortable; 8000K is bluish, and there is pink and purple on the look. It is better not to use it, it has no practical meaning, it is completely cool.

2. Replace the modified headlight assembly

Advantages: The same is simple to install, just replace the original headlights directly, beautiful appearance, and some add angel eyes and lenses

Disadvantages: Although some domestic and claimed Taiwan-made headlight assemblies have good shapes, the added lenses are garbage, there are bubbles in the lenses, the efficiency of the reflective bowl is low, and the focus is inaccurate. This results in a narrow illumination range and low brightness. There are serious light spots, and night-time vehicles have serious safety hazards. The installed angel eyes are mostly made of single LED light guide plastic, and the brightness difference is not obvious. There are also some large replacement assemblies of lamp manufacturers, such as HELLA and BOSH, which use high-end bifocal lenses. The quality is not said, but the price is unattainable, at every 7,000 yuan. , Is not acceptable to ordinary car owners.

3. The headlight assembly of the original car is equipped with a bifocal lens

Focusing on this modification, the simple summary is to open the cover of the original car headlight assembly, and then add the lens to seal the car. However, the requirements for this modification are very professional. Some car owners buy the relevant materials and DIY themselves, but the light type is very poor after the car is installed, and some even deviate too much. This is caused by the lack of professional positioning tools and methods. There are several difficulties in refitting a bifocal lens. The first is to open the lampshade. The headlights are sealed by hot melt glue and cold glue. The former is relatively simple and can be opened relatively easily as long as it is heated to a certain temperature, but the cold glue headlights It’s more difficult. If you don’t turn it on well, you can pry the headlight out of shape. If you reopen the lamp, the whole lamp will be scrapped. The cold glue lamp is represented by VALEO lamps. This is also a headache for professional changers. Professional tools are needed, and students who want to DIY are advised not to try it easily. The second is to install the lens positioning, this requires constant adjustment to copy the original data, which is also a key step. The third is to fix the lens, which requires scientific methods and suitable materials, otherwise the lens is installed in the headlight assembly, but it will inevitably result in a virtual position after a long time. The fourth is the sealing and wiring of the headlights, this will not be mentioned again. In short, every detail must be handled in place.

Advantages: The installation of imported bifocal lenses can achieve the illumination effect of AUDI BMW BENZ, but the price is a fraction of these headlight assemblies; users can make modification plans according to their own requirements and decide whether to install angel eyes or devil eyes , Whether the lamp bottom is sprayed black and whether it retains the original high-brightness style; after installing the lens, the xenon lamp will not diverge and have obvious cutting lines, the irradiation range is large, the brightness is uniform, and the solenoid valve is used to achieve the change of the shading plate to make a The light bulb realizes the change of the far and near beams, thereby adding a group of high beams, that is, 4 high beams (cars with independent light bowls), which increases driving safety at night.
