Car headlight modification, advantages and disadvantages of various headlights

Car headlight modification, advantages and disadvantages of various headlights 1

There are often many problems encountered when modifying car lights, and installing the wrong lights will cause unnecessary trouble to others and yourself. Everyone has heard about xenon lights or has seen them with their own eyes, so I will introduce them to you. Lamp modification.

Three types of headlights:

l Halogen headlights.

The light-emitting principle is the same as that of incandescent lamps, but incandescent lamps have a fatal flaw: the brightness is limited, and the tungsten filament will volatilize at high temperatures and condense on the outer shell, causing the bulb to turn black and affecting its lifespan. Therefore, people fill incandescent lamps with halogen element gases, which can effectively increase the melting point and lifespan of tungsten filaments. Under the same power, the brightness of halogen lamps can reach 1.5 times that of incandescent lamps, and the lifespan is also 2 to 3 times that of incandescent lamps.

l LED headlights.

LED has many advantages. Because it uses light-emitting diodes, it has the advantage of smaller size. It is also the favorite of designers now. It can be assembled into various shapes and is very flexible. But LEDs also have drawbacks, such as heat dissipation issues. If the heat dissipation is poor, the lifespan will be greatly shortened. Low-end LED lamps are less energy-saving than energy-saving lamps (cold cathode tubes, CCFL).

l Xenon headlights.

The English abbreviation is HID - gas discharge lamp. It is filled with a mixture of inert gases including xenon and does not have the filament that halogen lamps have. Its light-emitting principle is to form an arc between two electrodes through the starter and electronic ballast and emit light. Because xenon lamps have a start-up time similar to "preheating", it takes three or four seconds to reach the rated brightness after lighting the headlights. Therefore, do not use xenon lamps as high beams, and the high beam xenon lamps are dazzling and cause discomfort. Necessary danger.

Renovation is risky, so be careful when upgrading. We know that xenon headlights are very practical in daily driving, so we must pay more attention during the modification process.


Any modification or upgrade must first consider the safety of our drivers themselves. There are currently many brands of xenon lamps on the market, and it is estimated that there are at least 50 brands. Low-priced "bargains" often have a short lifespan, the transformer box and bulbs are easy to burn out, and the color temperature, brightness and scattering angle often do not meet the requirements. Such inferior xenon headlights not only affect their own driving safety , and also caused great disturbance to other people. Therefore, it is recommended that you choose brand car lights that are supplied by the original factory.

Finally, I would like to warn everyone that for the safety of themselves and others, they should refit in a civilized manner and not be stubborn in the pursuit of dazzling. You should also consider the other person's feelings when turning on and off the car lights, and do not respond to violence with violence. Civilization relies on mutual understanding. developed.
