I have had quite a few inquiries about my illuminated suspensions. instead of replying to each one I thought it would be better to add an image and some more text. I have made the suspension for an art exhibition to be staged in an underground vault in a June. The neon tubes are designed to fit around the speakers in cars and flash in time to music or any other sound input. They are inexpensive but hard to find a stockist. They run on 12volts
