Oral-b Professionalcare Does Your Oral-B Electric Toothbrush BLINK When Charging???

Does your Oral-B Electric Toothbrush BLINK when charging??? - oral-b professionalcare

My previous Oral-B Sonic Complete toothbrush that flashes while charging. I recently bought a 7400 Professional Oral-B toothbrush and do not blink while charging. It makes a difference, the version I have is white with a handful of dark gray (http://ecx.images-amazon.com/images/I/31 ...). My friend has an earlier version of the 7000-series, mostly on dark blue handles (http://www.smilox.com/smile/prdimg/oralb ...). His flashes while charging.

This is mine broken?
