I have an original Visuo Search light, available on Amazon and EBay for a few euro’s/dollars, mounted on the MM. It fits great. I made a video:

Hello and good day StephanO. Thank you for sharing this video you have made for the DJI Mavic Mini and for sharing this information with us. Have a safe and a happy flying always. .
I think a Vifly Beacon is all you need, strong light, long battery, tiny size and a crash sensor with super loud buzzer... they onkl weight 4-5 grams.
An user here "the saint" recommended it and I must say it's awesome!
