If the light does not flicker in front of your own eyes and only in the video, then it is the beat frequency between you shutter speed and the lights natural frequency which is close to each others. Try to change the shutter speed a bit and it should go away.

Shutter speed and the frequency of the power the light uses (if I recall correctly, most power operates around 50 to 60 Hz).

While getting started I flew a lot around my front yard and there are several LED perimeter lights around the house, sometimes lit in a cloudy daytime. I noticed that they all were flickering in the drone videos. That happens in designs that use pulse modulation in the lights like some LED's. Older 50 or 60 HZ incandescent lights do the same but to much less of an extent.

Hello there LoveYou. Good day and thank you for reaching out. Kindly please try to change the shutter speed on the DJI Fly application to see if the issue will still persist. Thank you.

Yeah, just as Gary said, some lights are just different. They have a different frequency other than those 50/60Hz lights and there's not much you can do about them in forehand. Maybe you can do de-flickering in post.

According to Google, the power mains frequency in Greece is 50 Hz, therefore choose a frame rate of 25 or 50 fps. That should solve your problem.

The modulation of LED light controls can be any frequency the designer chooses, not just the local line frequency. Some are many kHz.
