You are correct. Did some investigating today 2 are backbox. Then 1 for everything south of the pop bumper and 1 for everything north of pop. Ordering enough sockets to redo all the gi. Going to do all of the wht/yel string now and when I start having issues with the wht/vio I will redo that whole string. I was also thinking about how some of the GI could be moved to the top of the playfield for better light coverage. Example the gi that is where the 1-6 stand up targets are, do 3 of them under the aircraft carrier then throw one in between of the kickouts and pop bumper. Should produce more playfield light and would still be covered by plastics so cant see, My test LED came in also. Man oh man what a difference they make. I did 5 in the backbox and quickly realized my translight is waaay better than I thought. Going to go with 2 smd frosted naturals with a few 4 smd in some select spots. Its almost like it highlights the spot a bit with the 4smd without looking weird from being a different color.
