I don’t know why there aren’t more cables that light up, but I have to say that these iPod/iPhone charging cables look pretty sweet.
This cable runs from your iPod or iPhone to your computer or power plug. You’ll see neat lights running along the cable while it’s charging. The lights stop moving once the battery is completely charged.
You can see it better if you check out this video:
The lighted cable is available from az-import in either blue or green and retails for €19.99 (appx. $25 USD). They’re looking for U.S. retailers though, so you can get a much better deal if you buy them in quantity.
