Probably been mentioned on here before !, If so mods, feel free to remove it !
Just got a set of red, green, white Cree Strobes from Flytron.
My eyes are still recovering from initial switch on !!
My advice, get the decent 3M Dual Lock to mount them (they also sell that !).
I bought a 1 metre length from Amazon, now I can fit them to all the drones I have, and interchange the lights onto them when I need to.
