This Integral version of the Atto is specifically designed to be built-in fairings or any other bodywork. With its aluminum housing with an overall length of 13mm and a diameter of 9mm the Bullet Atto Integral is an ultra small taillight that re-defines miniature. Easy to overlook in traffic; you''d say; but the High Output power LED in combination with the special Extranz Extreme Optical Transparency technology actually gives it a colossal light output; when taking in account the tiny dimensions. Overall high quality and fully ECE compliant. This is THE ONE for those that like a taillight small and virtually invisible; until activated. Compatible with 12V applications. Dimensions: 13mm long x 9mm diameter. Wiring length is 70cm.
