Many friends don't know much about how the headlights of cars are modified when they are modified, so what are the parts of the headlights? In fact, car headlights is generally divided into three types, namely halogen headlights, xenon headlights and light-emitting diodes.

The difference between these three lights mainly depends on the color of the lights. Halogen headlights are generally yellow with a color temperature of about 3000K K, xenon headlights are white with a color temperature of about 4000K, and LEDs emit blue light with a color temperature of more than 5000 k.

Car modification is generally to change the front and rear combination lights, turn signals, front and rear fog lights and high-position brake lights. The front combination lamp has requirements for the light intensity and irradiation position of far and near light. It is also divided into two-lamp system and four-lamp system. All the lights in the car have different uses, so they can't be used indiscriminately or changed.

Night width indicator: commonly known as "small light". It is mainly used to display the width and length of the car body at night. Drivers should always check when carrying out maintenance. Some drivers think that the small lights don't work, so they just ignore them.

Signal lights: including turn signals and brake lights. It is very important to use traffic lights correctly when driving safely. The turn signal is turned on when the vehicle turns, and flashes intermittently to remind vehicles and pedestrians to pay attention to the distance.

And the turn-on time of the turn signal should be well grasped, and it should be turned on when it is about 100 meters away from the turning intersection. Driving too early will cause the illusion of "forgetting to turn off the engine" for the following car, and driving too late will cause the vehicles and pedestrians behind to be caught off guard.

Brake lights are very bright and are mainly used to inform the rear car that the front car should slow down or stop. If this lamp is not used properly, it is very easy to cause rear-end collision. In addition, it should be noted that the taillights of domestic cars are generally "dual-purpose" and there are two filaments in the bulb. Low light is a small light, and strong light is a brake light.

Fog lights can help drivers improve visibility when driving in foggy days, so that the opposite side can find the car as soon as possible and take measures to meet the car safely. Therefore, drivers must turn on fog lights when driving in foggy days.

Night lighting is also commonly known as "headlights". Headlights are the "heart" of all headlights. The rational use of headlights should be: turn to low beam when passing, and turn back to high beam in time after passing to broaden your horizons.

However, the headlights of some vehicles will age more or less after driving for a long time, which is very dangerous for driving safety. Therefore, it is recommended to pay attention to inspection during daily maintenance. Some drivers regard headlights as "weapons" and "sweep" them indiscriminately.

Many drivers often sneak on the road at night when no one is checking, and the headlights are extremely bright. Their headlights have been carefully adjusted to follow the car instead of the road. This behavior is very dangerous.
