Therefore, regulations require that as long as daytime running lights are equipped, they must be equipped with automatic headlights, and only if the lights are selected in AUTO The daytime running lights will light up normally only after the vehicle is in gear position.

6. Interior lighting may affect safety

Cars all have interior lights, also called reading lights. This light can only be used when parking and is best not used while driving, especially when driving at night.

7. Use the license plate light to charge the battery

If a car's battery runs out of power and the mechanical key is broken, how can you easily open the car door? Let me tell you a trick: you can remove the license plate light, then connect the positive pole of the power supply to the positive wire of the license plate light, and connect the negative pole of the power supply to the car body, and then press the unlock button on the remote control. You will find that the car door can be unlocked normally. .

The principle is actually simple, because many car license plate lights are controlled by the negative pole, which means that the positive pole of the light bulb is directly connected to the battery, and the switch is installed on the negative pole, so you connect the positive pole of the external power supply to the positive pole of the license plate light. It is equivalent to connecting the positive terminal of the battery, so it can provide power to the vehicle.

When driving, we sometimes need to flash the high beam to alert other vehicles or pedestrians. The specific operation is to turn the turn signal control handle in the direction of ourselves. But a few decades ago, the dimmer switch in many cars was controlled by foot. It was located at the lower left of the clutch. When you needed to flash the high beam, you just stepped on this switch. Drivers who could play with this light had poor driving skills. It will be bad.

9. Modification of automatic high and low beams

Some cars have an automatic high and low beam adjustment function. Although the original intention of this function is to automatically switch the low beam when meeting another car to improve safety, the actual use experience is not good because the sensor is too sensitive and sometimes It will misjudge the street light as an oncoming vehicle and automatically switch to low beam.
