Ok, that makes sense. The purple were actually pulled off the Herc and were supposed to be blue, I'll try a better blue and maybe a cyan and see how those look. As for being over/underdone, the Herc actually only has three glows, but they are really large. I was going for a more running-lights look (which made the most sense with where Nico suggested I place them, thus the red and green blinkers on the wingtips) and I tried to keep it subtile; maybe therein lies your dislike of them.
Also, I just looked again at the position. I may be able to pull the glows in a little tighter in places, so I'll give that a try.
