This listing is for a Metallic pro pinball machine LED bulb kit.  You will receive one green LED for the snake, one red for Extra Ball and now the correct Blue for Crank it up!  Blends in for a stealth mode.  Nice color and great lumens.  Hidden when not lit.  No ugly green plastic. 

This is the same size and shape as the old school glass 555 lamps in pinball machines.  Glass press and looped wires for exact fit in the socket.  Designed for DC 6V operation.  I have tested these in my machines over the past year and they are 100% solid.   Light beam is horizontal vs. shooting up in your eye.  

Thanks for looking!
