Very light weight, about 0.5oz a piece , LED safety lights, all with 5 modes......strobes, flashers pulse , concentrated light beam....red,whit blue colors
with different steady color or combinations. " attention getters " . Some will be attached to hull hovering from about a thousand ft to 500 ft. Other lights will drop down from hull at 100 ft intervals . Sound effects, like take off an landing plus an ominous invasion type sound ( got my Bose hid in the woods at edge of lake ). I like the sounds of the " Tripods " from " War Of The Worlds " , plus other sound effects. I'll go way out to float and fly over lake tonight when most people will be celebrating the 4th.
