The prop department used six big front lights and four smaller top lights arranged in two pairs. When the two top twin lights are lit up they appear as two big single lights because of their brightness. So you (falsely) believe there are 4 in some and 2 in others. There are always 4.
Progress on the ram will slow now, I have other projects needing my attention. The last detail I will add is the white covers for the LEDS, then it will sit until I get caught up on other projects. Then I will work on more detail. Coming soon will be a couple vids on the ram moving and a screen cap of the cam working.
