Using headlights experiences

So after we showed specific way of How to restore headlights permanently, these following experiences in using headlights will help you to ensure safety while driving.

1. For vehicles that do not have a headlight switch, when traveling during the day you should switch to flashlight mode or switch to fog mode so that the battery can be charged better.

2. On the freeway, if there is a high divider beyond the car’s lamp range, use a headlamp for better visibility. The divider prevents light from flowing between the two sides, so you will not have problems with the headlights.

3. In highways with low divisions, or with only solid lines or dashed lines, use light bulbs to move them, avoiding glare for vehicles moving in the opposite direction. If the road is open, turn on the headlights to see, but when the car’s lights go in the opposite direction, switch to flashlight mode within 150 meters.

4. Do not use headlights when the car, because if the opposite vehicle forget to turn off the headlights, the two vehicles at the same time will make the two drivers do not see the road, and the two cars will crash into each other. If you want to cross the car, do not stick the tail with the headlights, so maintain a safe distance and rock the lamp to signal over.

5. When going on the road or needing to pass or reminding other vehicles to lower the headlights, the headlights should be used in the open type. In cars, the headlights sometimes work better than horn cars, as cars on the move are usually closed and difficult to hear the sound of the horn. While some gleams of light come into the rearview mirror, the driver easily recognizes the car behind.
