The Blinder 600, 900, 1300, Blinder E range (front lights) & Blinder X range have two mode types - flashing and steady. To change between the two mode types quickly double press the lights button.
If your Light only seems to have flashing modes or steady (non flashing) modes, when the light is turned on if you quickly press the button twice this will change between the two mode types. You can then single press the button to find your preferred mode from the available range.
If you have an StVZO version light (sold in Germany), these lights do not have flashing modes as per StVZO regulations.
