I've been searching for this for quite some time but I cannot seem to find one. I'm looking for a small self-contained LED strobe that I can mount on the phantom's battery door to help with orientation. I don't want one that has to connect to the lipo battery, I need it to be self contained and run on its own small battery. It must be small enough that I can mount it with double sided tape on the battery door and turn on and off manually. Any ideas?
