The other day I responded in this thread ==> chest light sequence regarding the 'correct' ROTJ chest light sequence:
Here are some images from the movie where some light is visible on the upper part of the chest light:There's no 'correct' ROTJ sequence because most of the times the chest light is barely visible or not working at all, especially in the outside shots. The only time you can see some light 'sequence' is in the Jabba's palace scenes, but from my investigation, mostly just the upper part is lit and the lower section is almost invisible
It seems that the chest light lit up then goes off and then again on. Each sequence contains the correct upper light, but the lower light is 'borrowed' from the ESB chest light sequence (thread here ==> ESB Chest Display Sequence) and from this image (stills from ROTJ) they look pretty close:
Even in these images the lower section is not as bright as the upper section, this is why I represented that part with darker colors. And because there are no clear(er) images to prove the exact sequence of the lower section, here is my representation of the ROTJ chest light sequence (using the ESB light scheme):
Remember that this is my interpretation and is not written in stone, or even accurate. Use it at your own risk!
