I noticed that the TOS-R versions of "The Cage" and "WNMHGB" have the nacells painted red and not glowing. I always figured that the engines were supposed to glow. The early models of the Enterprise had very limited lighting systems. In fact, The Cage version had no lights at all. However, that was an issue with the model (which was improved for the actual production). So I'm wondering if anyone else thinks that the TOS-R enterprise should have been given the glowing engines.
