the X-01 light is cast from the eyes, and you can change the color of the eyes by changing the color of the lamp
I like that it's cast from the eyes, since it's a cool effect.
But at the same time, I'm also certain it doesn't make any sense for you to be able to blast highbeams through the eyes and the person inside actually see through it.
And it's a shame it doesn't show the beam of light, like the headlamp on other armors does.
That would look extra cool coming from the eyes.
