Kellerman Atto Stop/Tail

The Kellermann Atto® DF is a game-changer for Triumph Modern Classic riders who want a minimalist, ultra-clean rear end without sacrificing function or safety. This tiny unit combines indicator, tail light, and brake light in a single, street-legal package—making it the smallest ECE-approved 3-in-1 light on the market.

Barely visible when off, but unmistakably bright when on, the Atto® DF is ideal for custom builds where less is more. Whether you're trimming down a Bonneville, Thruxton, Scrambler, or Bobber, this unit allows you to ditch bulky OEM lighting without compromising on safety or legality.
