The FAA requires anti-collision lighting for flying during Civil Sunrise, Civil Twilight and Night operations. It is also a good idea to mount lights during LAANC operations. There are many options but there is only one product with the right brightness, right design, and amazing customer service: Firehouse Technology Arch V! American made with 1000 lumen output these LED lights can be seen for at least 3 SM and can be mounted on all DJI drones with custom 3D printed mounts by Aerial-Pixel.com. They are also perfect for light painting! I love these lights and this company.
