In ESB (all official versions) the lead walker has a red light on in one shot and not anywhere else.
The ROTJ example too is for one shot.
Ady went to great pains to remove that one shot in ESB.
In ROAST all the walkers seem to have the red eye, my (post suggestion closure) suggestion was that very briefly we see the light activated confirming that it’s not the default setting, it’s something that happens once in a while for an unexplained reason to try and reconcile what appears to happening. But Ady has already said the ST doesn’t figure into his revisited plans and it’s highly probably that the same is true with the spin offs. The first two trilogies are known things you can’t fix the yet to be made. By the time Ady completes ROTS:RE we will probably be on the SST
