Quoted from Diospinball:
The N for Night Moves seems to be out most of the time, but then it popped on a few times, but then back off. N never works in attract mode though.
The I seems to be working in attract mode but sometimes it doesn't work in game. And those are on a special board it looks like.
Any idea how to remove that board and/or change the lights on it?
To take the lamp board underneath the NIGHT MOVES inserts off, you first remove the connector from it. There's a small latch on top of these connectors that you push while you pull the connector out. Then remove the connection on the four corners of the board, either by squeezing the white connection things through the board, or by unscrewing the screws that go into the playfield.
Once the board is removed, you'll discover that every insert has 3 lamps. The middle lamps act like regular controlled lights during attract mode and gameplay. The game uses these middle lamps the most.
The outer lamps give a flashing effect during certain parts of the game, i.e. during multiball. The game uses these far less.
I fitted the outer lamps with bright, colored leds in a rainbow pattern when I had the game. This made the effect they gave much more noticable and enjoyable than the regular 44's did.
