Though, I thought EL Wire (at least, the stuff consumers can get their hands on) is sensitive to UV light and leaving it in the sunlight (in the Earth's atmosphere!) reduces its lifespan. Space would be the wrong place for that stuff, assuming that they haven't taken this into account.

EDIT:

Looks like the suit is for ground testing only, though this would still apply if they're using it in the sunlight.
