Halloween fun ahead! Perfect for all your haunted house needs, or for good times at your non-haunted home or at events! These mini strobe lights are awesome for creating amazing party effects like in the best bars and clubs, or the most terrifying scary effects like in amusement parks and movies! These are small, featuring 3 lighting tubes, and meant for home and recreational use. You can adjust the blinking speed, and can be mounted to walls and ceilings. No batteries required, just plug into any wall socket and turn on/off with switch on cord!
