The Kellermann Atto series give new meaning to the word downsizing. With a length of only 14mm and a glass diameter of 7.8mm Kellermann indeed redefined the design. The light surface of the Atto would fit four times on a cent coin, just to visualize the size. This new definition of minimal size opens up completely new design possibilities on the motorcycle, because the factor turn signal, is almost eliminated. However, you must not underestimate its capability, because it delivers astonishing luminosity with minimal size! Parallel to the well-known High Power LED technology, this indicator incorporates the EXtranz technology (Extreme Optical Transparency). The entire electronics are contained in the metal housing and can thus be connected directly to the 12 V power supply.
