I wanted a strobe light on my Typhoon, so I did this mod. Hope it helps. It can be adapted for most any drone. Pictures in the zip file should be self-explanatory. I made a short video clip to show how it can be seen in full daylight from a distance. The light itself is about $10 from WalMart, brand name Schwinn. It is a USB rechargeable strobe/steady light made for bicycles. I used a Dremel tool to remove the strap that came with the light. Then I used Velcro to attach to the drone. I chose that location so it points to the front, but you can put it wherever you wish.
Enjoy!
Enjoy!
