Set your trap with LED light trip wire beams that sound an alarm when triggered.
This fun spy-themed set is great for catching out the unsuspecting or protecting your room from siblings. Set up the two beam transmitters up to 4 feet away, perfect for doorways, to easily create your customised laser barrier. The two adjustable LED beams connect with the receiver which then sounds the alarm, set to either loud sounds or a silent flashing light. Catch an unwary parent!
