First of all, it is extremely difficult to photograph a pinball machine with LEDs. Almost every pic I have seen looks a lot worse than the seeing the machine in person. I have LEDs in all of my machines now, and I would never go back. I am using the LED OCD (made by one of the guys on Pinside) board to smooth out the insert lighting. It looks fantastic. I am also using LE kits from pinballbulbs which include spotlights and LED strip lighting in addition to the bulbs needed for the machine. the whole playfield is nicely lit up, so the individual LEDs are not overpowering. AC/DC is well lit by design, and these kits really update the look of the older games so they fit in with the new stuff.
The purples and blues are not anywhere near this harsh in person, but this is about the best I could do taking the pic. In person, they look great, even playing in a dark room. If you have seen AC/DC in person, you can tell the difference in how it is captured in the pic. It is a similar difference in the other pins.
