This is made from a gold plated fuse, used in high end stereo for superior sound quality. They have such a great look - atompunk/mid century - I didn’t want to really alter the look. The internal gold plate “S” connection has such great form I couldn’t improve on it.  I’ve sold several attached horizontally on a cord for men’s jewellery.  Audiophiles love them.

But I wanted to highlight it with light.  On the bottom of the fuse I’ve installed an LED with a connection post running through the base cap.  The light is turned on by plugging that pin into a small silver tone battery pack.  It holds tight to the pin.  The battery pack unscrews at the top so batteries can be replaced.  The bracket holding the fuse is not fixed so you could turn it up the other way and have the battery pack on the top of the fuse. To balance the piece without the battery I created a similar post on the other end.  

Why should fun jewellery, brave jewellery design using light be the domain of gaudy kitsch - plastic flashing Christmas earrings, disposable dance/rave accessories and cheap novelty toys for kids?  Why can’t it be used in high quality unique design?  Yes, it’s a bit mad scientist and will certainly attract attention whether the light is on or off.
