1. Compared with halogen lamps, the brightness is increased by more than 300%.

2. The tungsten-free structure also makes the life longer than that of halogen lamps.

3. It is more energy-saving and environmentally friendly than halogen lamps, and the power loss is saved by more than 40%.

4. If there is a fault in use, the xenon gas will not go out instantly, but will gradually dim until it goes out. This gives the driver on the road time to deal with a headlight failure.

Disadvantages of xenon headlights:

1. The light-gathering performance is poor, and because it is too bright, it is easy to shake the driver of the opposite vehicle and cause an accident. However, the current xenon headlights are basically equipped with lenses, so this problem can be solved. But as far as I know, the Accord's xenon headlights are not equipped with lenses.

2. The penetrating power is too poor. In fog and snowy weather, the penetrating power of xenon headlights is very weak.

3. Delay effect. Because of the working principle of xenon headlights, it takes 2-4s to light it. When driving at high speed, the horn is often useless, so it is necessary to use the headlights to "shake" the vehicle ahead. At this time, it is completely impossible to rely on the xenon headlights. Therefore, some manufacturers use this as the interface, the low beam uses xenon, and the high beam still uses halogen.
