USB light

Knog's Blinder front LED light certainly lives up to its moniker. 88 lumens sound distinctly average by this season's standards but the choice of lighting patterns seems to grab the attentions of approaching traffic faster than conventional blinkies.

Dropping its podgy medical grade silicone in favour of anodised aluminium/sturdy resins has bolstered its build quality too and it's been the only USB plug in that I've been bold enough to hosepipe test at close range, let alone fully submerge!

Bright, brash and now USB chargeable, Knog’s Boomer is certainly bright enough for city and suburban streets and dark lanes with reliable output and charge-times- it even survived five minutes continuous onslaught from the garden hose but so do many others and the silicone bracket is neither secure, nor particularly versatile when it comes to mounting the rear version tested here – we've also included technical details of the front though because USB recharger apart it is identical to the Boomer front light we've already tested.
