5.The door and door switch are not in contact.

There are a variety of reasons for:1. The vehicle's sensor bulb is damaged.

2. The sensor of the sensor lamp is damaged.

3. The circuit system of the induction lamp is damaged.

4. The safety system of the sensor lamp was damaged. After the sensor lamp is damaged, it needs to be inspected and dealt with according to the simple to complex reasons.

The induction lamp used on the motor vehicle is to turn on the lamp by induction, when there is a problem with the induction lamp of the motor vehicle, it is necessary to use the method of investigation to check the position of the induction lamp, start from the line, and finally check the lamp source of the lamp, after finding the specific problem, the symptomatic repair, and the vehicle can be restored to normal use after maintenance.

1. Turn on the double flash switch to try if the light is on, if it is on, the problem lies in the turn signal switch part; 2. If it is not lit, see if all the 4 turn signals are not lit, if the problem is on the bulb, it will generally not be broken together; 3. The biggest possibility is the line and the fuse, check these two.

Are you talking about vehicles that are in sale status?

Reading light = overhead light?

Plug in the power = key to power on?

Use the switch = top light switch to turn on (off, auto gating, on)?
