Own a Mavic Pro and a Mavic Mini. Sometimes they become hard to see. Are aftermarket lights a possible solution?  Other suggestions welcome.

I use these;

Easily visible in strong sunlight to around 250 meters, at sunset to VLOS+. Different colours so drone direction is easily identified without screen.

If you need more light I would recommend the latest lume cube.

don't waste your money on them strobe lights, got rid of them.

Why the negative reply?

One charge (USB) provides 2 hours of use.

15 quid a light.

In some countries VLOS cannot be aided with anything so maybe just changing its color is enough.

just stating my opinion, had two lights one on the front and one red at the back but you just can't see the lights when the drone is far away from you, that's all,  so I got them off, besides I really don't like to attach something to the drone, your choice buy it or not, not being negative mate.

I fly with Firehouse Arc 2 strobes on my M2Z. A white one on the bottom, and a red one on the back. The strobes are very bright and very light and do not hamper the flight characteristics in the least.
Very easy to see in the daylight, and outstanding in low light.
