Traffic Jam Traffic Light Earrings are bare printed circuit boards designed to allow you to see the beauty and art of electronics. They automatically sequence from green to yellow to red, and then back to green again, just like real traffic lights!
How to Care for Your Earrings:
Your earrings are open PCBs (Printed Circuit Boards) with delicate surface mount components. Please make sure not to place them on metal surfaces, or store them together with each other or other metal objects like jewelry or keys, which may cause them to short circuit. When they are not in use, it is best to store your earrings in their individual static dissipative bags.
Don't let your earrings get wet, they'll drown!
When the included batteries wear out, they can be pushed out of their battery holder with a paper clip. Two new CR2016 batteries can be stacked on top of each other then slid inside the earring. Please make sure that the positive (+) terminal of each battery faces up towards the metal cover of the battery holder, and the negative (-) terminal of each battery faces down towards the PCB.
