Incandescent 455 Blinking Bulb

  • $1.99

The original 455 incandescent blinking bulb!  These bulbs truly blink randomly in a classic warm white.  Fits any standard 44/47 bayonet socket.  

These bulbs work by using a bimetallic strip to complete the circuit.  As the bulb heats up this strip bends, disconnecting the circuit.  Once the bulb cools down the strip again makes contact and the process repeats.  SO COOL!

These bulbs are also needed for delay relays often seen in many Bally EMs (to control buzzers, slam tilts, etc.).
