Knog lights have long been held in high regard for by commuters, and it’s easy to see why with the simple and effective Knog Blinder Mob Four Eyes rear light.
While its big brother, the Knog Blinder R70 rear light, is aimed at out-and-out roadies training at night on pitch black lanes, the Knog Blinder Mob Four Eyes rear light is aimed more at commuters riding under street lights, and in this situation it does a great job.
With a brightness of 44 lumens, there are certainly brighter rear lights on the market, and yet the Knog Blinder Mob Four Eyes rear light is still more than bright enough to stand out when riding in the city, even against a background of red brake lights and traffic lights. In fact Knog says that it can be seen from up to 1.2km away.
There are five different modes to choose from (two constant, two flashing, and one strobe) which should have you covered in all riding situations. Cleverly, the light also remembers which mode you were in when you last turned it off, and will start in that mode next time you turn it on.

The only thing I wasn’t entirely sure about was the exposed USB charger. This forms part of the mounting mechanism, meaning that it is exposed to the elements.
Knog says that the charger is waterproof and won’t be damaged by exposure, which in my experience seems to be the case. However, what I’m not so keen on is that the plug is likely to pick up mud and grit from the road, which will then be transferred to the innards of my laptop when charging. The solution, perhaps, is to use the supplied USB extension cable, which also makes it easier to plug into USB ports.
Much better is the fact that the Knog Blinder Mob Four Eyes rear light is supplied with three different sizes of strap, meaning that it will easily fit all but the very deepest of aero seatposts.
I was also impressed by the battery life. Obviously this depends on what mode you have the light on,so it will only last for two hours if you choose to have it on the highest constant mode, but if you stick to the Eco Flash mode (which I would still feel very safe using in all situations) then it will last for up to 66 hours, which is probably enough for at least six weeks of riding for most people
