Kellerman Atto Indicator/Stop/Tail

The Kellermann Atto® DF is the go-to lighting upgrade for Triumph Modern Classic owners aiming for a clean, minimalist rear end. This compact unit combines indicator, brake, and rear light into the smallest road-legal housing available—ideal for custom builds that echo the days when motorcycles didn’t even come with indicators.

Invisible when off, eye-catching when on. Thanks to Kellermann’s HighPower LEDs and EXtranz® optical transparency tech, the Atto® DF offers remarkable visibility despite its size—keeping your bike safe without spoiling the look.
