The Atto® DF is the newest and most spectacular member of the highly
successful Atto® family of Kellermann. The Atto® indicator and Atto® RB
rear/brake light, already defined a completely new category in the
motorcycle lighting segment. The Atto® DF now offers all three functions
fully street legal in one product – simply put: 3in1! Moreover the Atto®
DF is as small as all members of the Atto® family: the illuminated
surface fits four times on a tiny 1 cent coin!
