Kellermann Atto Turn Signals

The Kellermann Atto series stands for maximum precision in minimal space. The active light surface of an Atto indicator fits four times onto a one-cent coin – it hardly gets any smaller than that. With a housing only slightly larger, the Atto opens up entirely new possibilities in motorcycle design. Especially for Harley-Davidson conversions, classic restorations or custom bikes, the visual impact of the indicator becomes practically negligible.

Despite its compact size, the Atto delivers impressive brightness. This is made possible by a special electronic circuit, which Kellermann has even patented. It ensures maximum light output and uniform illumination.

All electronics are housed in a robust metal casing and can be connected directly to the 12V on-board system. This saves installation time and guarantees reliable operation even under tough everyday conditions. As with all turn signals that have lower wattage than the stock ones, you’ll need to check if the flash rate stays within spec. On Harley-Davidson models, this can usually be fixed by swapping the flasher unit or installing a Badlands load equalizer.

The Kellermann Atto is therefore the ideal solution for anyone who wants uncompromising functionality with a minimal look – whether for faithful restorations or high-end custom projects.
