Using thermochromic inks, it is possible to have cords actually change color to reveal written 'warnings' or messages
Using wrap-around labels, allows for easy retro-fit of existing cord sets
Labeling can be made as either as a reversible color-change and/or permanent (irreversible) change once a certain maximum temperature is reached. Irreversible inks may have extreme temperature trigger settings and also be used for warrant-void proof
