Knog Frog Strobe

By Patrick Engleman

Knog Frog Purple & White

Knog is known for their flexi silicone bodied waterproof lights that some have termed hipster cysts for their popularity with city commuters, but don’t let that detract you from a great four-mode safety light. They are right at home on your grocery getter due to their low $17.95 MSRP and you could almost feel comfortable leaving them on while visiting the grocery store or corner shop.

I used both the red and white version of this light in a previous incarnation and they were not as bright as the retinal burn you will achieve with this new model. I did a test with my dog to see which light she barked at more, and it was certainly the new model versus the old single bulb version. I thought the dog was a better choice than stopping random drivers along my commute to ask them about the 25-lumen beacon of safety attached to my ride.

Drivers will see you coming from well beyond the claimed 600 meters due to the high-powered, surface mounted, light emitting diodes encased in the stretchy, form-fitting silicone body that flashes in four modes, described as strobe, disco strobe, epileptic fit strobe and constant. The lights come in 12 different colors, so there is no outfit you can not match to your lights. With a claimed burn time of 80 hrs (flashing), 50 hrs (steady), you will have many trips around town on your tires before you need to replace the included battery.

One benefit that I noticed beyond the performance of this 19-gram light is that they are no longer using the barely recyclable hard plastic packaging that the lights used to come in. They were a neat shape and size, but not useful for anything and sort of wasteful. The new packaging has minimal plastic and the majority of it is made from recycled material that is easily chucked in the recycling bin. Extra points should be awarded for thinking green.
