This is a set of 7 LED lamps for arcade game controllers, such as DAO controllers. They use WS2812B LEDs, and pressing a button on the board while the lamp is lit will change the color to one of 9 different colors. They use T10 sockets and should work with anything that uses 5V. These are handmade, so there may be slight variations in the finish. There is some flux residue. *Due to a violation notification, the default is now a set of 7. Other quantities can be arranged via comments.* Current stock: 22
