My $.02... and to be 100% truthful - this is mostly conjecture... They used LEDs in the sockets but they weren't lit. They likely had the intention of using them as light points for the fx... but like the fiber optics in the X-wings gun tips it didn't work out well in Film.. The lights were too bright, so they weren't used.

That sounds about right because when I used the clear acrylic rods, I had to turn them down quite a bit to get them to fit inside the tubes. It would have been a lot easier with just LEDs because the wires could have fit easily inside the tubes.Jedi Dade is quite right. They did use orange/amber LEDs with the rounded edge turned to have a bevel.
This information was confirmed by two different people (both here on the RPF) that had first hand, close-up inspection of a few of the original filming miniatures, including taking actual measurements off these models.
Vince,
very nice workmanship!
I love your attention to detail,
... also nice website, those jumpsuits, look great.
It sure looks to me like the LEDs are lit up here. They have a bit of color, and there is some glare that wouldn't be in the animation effect.One reason why I was thinking about white lights is due to the scene when the Vader TIE Advanced shoots at Luke's X-wing. The orange blasters give off a pulsating, white light. It may have just been another special effect, like the green bolts coming from the TIE fighter blasters.
