Product Description
The long line on the left behind the handle holder bracket outside the car door is usually the power cord used to connect the lights or alarms inside the car door. The working principle of this long line is to provide power supply for the lights or warning devices inside the door by connecting the power supply, so as to realize the lighting or warning function when opening or closing the door.
The specific working principle is as follows:
1. Power supply: the long line is connected to the power supply system of the vehicle. When the door is opened, the power supply is transmitted to the light or alarm inside the door through this long line to provide the required power.
2. Lighting function: If the light inside the door is connected, when the door is opened, the light will automatically light up to provide lighting assistance, which is convenient for passengers to get in and out of the vehicle or find items such as switches at night.
3. Warning function: If the alarm inside the door is connected, when the door is opened, the alarm will sound or flash to remind pedestrians or other vehicles around, thus increasing the visibility and safety of the vehicle.
Generally speaking, the long line at the rear left side of the handle holder bracket outside the car door is connected to the light or warning device inside the car door to realize the lighting or warning function when opening or closing the car door, thus improving the visibility and safety of the car. Maintaining the normal connection and working state of the long line plays an important role in the normal operation and driving safety of the internal equipment of the door.
