How to solve the problem that the led light is still dim after turning off the switch?

After turning off the switch, the LED light is still slightly bright. The following measures can be taken to solve this problem:

1. Check whether the switch is damaged: if there is poor contact or damage inside the switch, the switch will not be able to completely cut off the power supply, leaving the LED light still slightly bright. The switch needs to be replaced at this time.

2. Check whether the line leaks electricity: If the line leaks electricity, the LED light will still be slightly bright. At this time, it is necessary to check the line, find out the leakage place and repair it.

3. Check whether there is a problem with the LED lamp: If there is a problem with the LED lamp, such as internal component damage or circuit failure, it will still be slightly bright after the switch is turned off. At this point, the LED lamp needs to be replaced.
