If you buy the proper LEDs from Pinball Life, make sure the description states that they will work in AC or DC circuits...the cheap 39 cent bulbs are for DC only and do not mention this. Don't ask how I know. 
As sold by Pinball Life, the proper ones I linked to previously are set up for 6.3 volt AC use. Just install as you would an incandescent 44, 47 or 55, and enjoy.
I conducted an experiment today. I managed to completely recap, recarb and rewire a 42-22CL chassis in 2-1/2 days. A new world record. I'm getting this set ready for Kutztown. But anyway...I installed an LED miniature bayonet lamp into the lamp socket in place of the 47. Now, this is an AC/DC chassis with a series filament string, but it has a resistor with one section having the 47 connected in parallel with it. The LED worked! It didn't get too bright and didn't really dim much as the filament string heated up. I put a #47 incandescent back in afterward, but this is good to know.
