455 Blinking Comet LED

Choose base, colour, and blink speed using the drop down menu.

This is a blinking bulb. They are commonly used in backboxes, especially EMs. If your game calls for a #455 or #545 bulb, it’s just an artistic choice. The socket works just like a regular bayonet 44/47 socket. It’s the circuitry inside the bulb that makes it blink, not the socket or voltage delivered to it. (So it’s okay to use blinking bulbs in sockets that had a non-blinking bulb, or to put non-blinking bulbs into a socket that called for a blinking bulb).
