Aquarium Safety of UV reactive "cable sleeves"?

those cable sleeves are definitely safe, as they cover the tubing; they have no water contact.

However, I dont see how you'd get them to glow....I have UV reactive tubing in my computer and they need to be under a UV light to glow.

one would assume that he is going to put a UV light in his hood or something, with which to make them glow :D
