The Knog Blinder Road 400 offers a 400-lumen output, a range of modes and simple, tool-free mount. The two buttons are also useful for changing between modes quickly but are a little tricky to use when wearing thick winter gloves and the light’s on the pricier side.
The Blinder Road 400 is Knog’s second brightest light, behind the Blinder Arc 640, and attempts to bridge the gap between a light with which to be seen and a light to see by. Despite it’s relatively small size, the Blinder Road’s output puts out plenty of light and it does so via via two LEDs. 400 lumens isn’t quite enough to regularly use it as a dedicated night riding light, but enough for the occasional dark or unlit road during a ride, or to use as a secondary/back-up light.
The two LEDs offer a narrow or wide beam angle respectively and can be used independently or together, with high, medium and low brightness settings. There are also two flashing settings, which makes for 11 modes in all – an impressive for a light of this size. However, there’s very little in the way of dedicated side visibility, with the LEDs sunk into the front of the unit.
