Actually my own recommedation is different.

Having steady rear lights mounted at the socks/ankles is the way to go. The movement of the feets makes you instantly recognisable and standing out from very far away. There is a (australian I believe?) company that sell pedals with integrated lights too but I can't remember the name.

I am still using a regular rear light powered by a dynamo hub though, as batteries can always die without warning.
