A bit on the pricey side though but yeah they are neat. You can make the same thing for about a fraction of what they are charging though if you made your own and you would have a more custom unit. Email me if you want the list to where to buy your pieces to build your own, I'll gladly direct you to the right sources and places to buy the pieces. And soldering isn't as bad as it might seem the first time out. I produce LED prop eyes, blinking and non-blinking for the haunt industry as well as other venues outside haunts and have the experience building items like this, as I deal with them every week. Let me know and I'll post the list here or privately in email.
Thanks and be safe.
About HSE: We are a small haunt prop company run out of our home and located in central Indiana that sells props from DVDs, to Audio CDs and is working towards opening the biggest and best haunted event in central Indiana. With over $25,000 in props so far, we are striving to be the best haunt experience in the country. We started doing haunt props and CDs/DVDs to sell during the October, 2003 season. The props are made by myself and my wife, Karen and all funds raised goes towards helping us fund our coming haunted event that is scheduled to launch in Sept, 2016 here in Indiana. We provide props to both pro and home haunters as well as those just wanting a prop or two for their home during the haunt season. Hallow Screams is our coming haunt event, and Hallow Screams Entertainment is our props company side.
