Product Description

Most real frogs don?t come in 12 colours; most wouldn?t have a flexible, silicon body; and most don?t have a bright LED built into them. But as we learned from Jurassic Park, nature finds a way - and I suppose when it does, our Knog Frogs won?t seem quite as amazing. Flexible silicon body with an integrated clip feature allows for quick mounting (ideal diameter 22 to 32mm). 4 modes: Constant, Strobe, DISCO Strobe, Epileptic Fit Strobe. Uses 2 CR2032 batteries (included). 19 grams (including batteries). To be used as a safety light only. WHEN USING FOR THE FIRST TIME, MAKE SURE TO REMOVE THE PAPER BETWEEN THE BATTERIES.

This review is from: Knog Frog Strobe Rr Bike Lights (Sports)

I had read a lot of reviews about this item and most of them said these little Knog Strobe lights were difficult to use or broken.

Straight out of the package there are instructions that tell you to take the batteries out and remove a small slip of paper in between them. This most likely prevents them from turning on while in shipment. I noticed fiddling with it that the light came on for a split second even while the paper was in between the batteries before I had taken it off. I pressed down on the top (to turn it on) and probably resulted in a weak connection between the batteries around the edges. Maybe this is the reason a lot of people said their Knog was broken or couldn't get it to work properly at first.

The next complaint I read was that the lights turn on a lot in their backpacks. So far I have only had one of mine turn on once, but I have to argue that this is a pretty common problem with most lights. I used to have a Planet Bike brand beamer and tail light and they'd always turn on while in my bag. I'd say that it really depends on how you handle your backpack (I'm pretty rough) and that you should just make a habit of checking your lights when you get to your location and put your bag down. The buttons aren't finicky at all or difficult to press down like some reviewers said. They do take a moderate amount of pressure that just rolling around in your backpack generally wouldn't click them on, but not enough to have to fidget with it every time. There is a "click" sound when the button is pressed to leave any doubts about whether you pressed it correctly or not behind.

The last complaint I read was about the 5 different options for blinking style. One other reviewer posted the solution: select the blinking style you like (I like the steady even blink) and then when you turn of your light every time just hold down the button until it turns off and it will effectively save that style's position. Every time you turn it on after that it will start on that blinking style. You have to be sure to hold it down every time you turn it off though or it will lose the setting (and start back at the first style again).

Overall, the lights fit snug around my handlebars and seatpost and I have not had any dead batteries yet. I just wanted to clear up some misconceptions I saw on here.

This light is perfect for the casual after-hours commuter that just needs to be seen while riding at night.

Pros: Very small, secures tightly to seat posts or rear racks, can be pulled off in a second and dropped in a pocket or switched to another bike in your stable.

Cons: Not the brightest light available. Fairly directional light so while you can mount it just about anywhere, pointing it towards traffic coming at you is a bit limited. Does not double as a reflector.

I'm using this light on my road bike. I rarely ride before or after dark and wanted the smallest most convenient light I could find and this is a winner for that. Now if I get caught riding too late I have something to keep me a little safer. The light is bright enough to keep you visible to motorists and the flashing mode does draw attention. Motorists seem to love flashy text messages and GPS systems in their cars and this light should draw their attention away from those long enough that they see you and don't run you over.

Because it's a single LED light and somewhat directional, it's not very valuable for daytime usage. If you want to maximize safety, go with a heavier light that has multiple LEDs, larger batteries (this uses two tiny CR2032 batteries), has a built in reflector and can be seen from more directions. I recommend the Planet Blinky series for that.

However if you're looking for a nice little light to make you visible at night and only need to use it occasionally, this light is an excellent choice.

4.0 out of 5 stars good for rear light, could be brighter, November 26, 2010

This little guy does the job of blinking to notify drivers that there's something ahead of them. The Knog light is great for a rear light, but I also bought the same size for a white front light....not bright enough to light your way on a street. Good for cars seeing you, not enough for viewing a dark road.
