      Fantastic light for a fantastic price. Buy it!

      As my job requires me to be up and about at all hours of the day I've long abandoned my car as a method of transport. If I need to be in the hospital quickly the last thing I want is to be stuck in traffic twiddling my thumbs. Thankfully I live close enough to work and own a decent bicycle. MY cycle to and from work takes about 10 minutes each way and is along well lit roads with dedicated cycle lanes. I have it pretty nice I must admit but I still need to protect myself against the lunatics on the roads at 6am!

      Thanks to the councils well lit roads I don't need a very powerful lighting setup on my bike, I get by with a set of LED lights no problem. My sister gifted me a red Cats Eye LED light last Christmas which has kept me visible on my way home. Unfortunately my front light kicked the bucket after an altercation with a railing one wet and miserable day. Reading a couple of reviews on here and on cycling websites I decided to buy the Knog Frog Strobe Front Light.

      A tenner on Amazon with free shipping is a good deal for a reliable bike light. Despite their small size LED lights can be deceptively expensive when the time comes to part with cash! For a tenner though I'm quite happy. The packaging claims 80 hours of life so I'm looking forward to quite a number of cycles before replacing the batteries!

      The light itself is made of coloured rubber (a tasteful bright orange in my case - saves me finding it in the dark!) and has a small opening where the light sticks out. The rubber shell has a loop which wraps around your handlebars and attaches onto a small clip on the back of the light. It sounds rickety but it's far more secure than any screw on model I've owned and the slight give in the rubber material allows the light to absorb some impacts instead of simply giving way.

      Operating the light is simple. Just press the button on the top to cycle between the different modes. The light has a constant setting and a number of different timed flashes. I tend to use the simple on-off mode which has guided me home safely since I bought it! I can image as well that the battery life will be preserved longer in this mode compared with constant. The light itself is very bright for such a small item, it really does make you visible to oncoming traffic. The alternating flashes are very useful at this at attract the attention of any oncoming traffic.

      Overall this light is a great purchase and will see you safe on your bike for a long time and for a bargain price. If I was to make an improvement I would perhaps make the loop slightly thicker as it can feel a bit flimsy in my hand. I'm pretty sure it won't break but I'd still like to be sure!

      5 Stars easily.

      Amsoutely amazing; extremely powerful; 100% better than Calssic CatsEye Lights

      Make: Knog

      Type: LED
      Size: same as 50p

      Price: For a set on Amazon, it cost be just £8 but they usually cost £12- 14


      I've tried all sorts of lights for my bike but they always fall off, break, get water in them or aren't very bright.
      I was searching the Internet when I stumbled across 'Knog frog' lights. However on the photo I saw they were only about the size of a 50p and so decided against. However, one morning I woke for work and it was still dark. A probing blue light shone through our door where someone had left their bike light on. On inspection it was a Knog frog so I bought a set.
      There are by far the best lights I have ever had. It is basically made of waterproof silicone rubber available in a variety of colours. The led light is flat like a button with just a small opening for the light to pierce through.
      Attached from side to side is a sort of rubber band. They are so easy to attach. You literally wrap the band around you handle bar as they are elasticated, and then hook it over a small clip on the led light. It takes a matter if seconds and they are really secure.

      Secondly the light is astounding. It's incredibly powerful for such a small light. The beam lights up the whole street so not only can you be seen, but you can see also. There are two setting: constant beam or constant flashing. To activate, simply press down on the top of the light. The rear light is red and equally as visible and powerful. These lights can be seen from up to 20 metres!
      You can also buy the original Knog Frog which have just a small circular LED light. They are the same size and still really powerful. These are so convient; I can take them off and out them in my pocket to stop someone thieving them when I get off my bike. As I mentioned, the flat light is the size of a 50p, with the elastic band reaching 5cm out to look like a sort of catapult. With them being so flexible, you can basically wrap them around any part of your bike.


      What's more, LED lights are much better and much more powerful. The batteries (watch batteries) don't run low as quickly as normal batteries. To replace, you simply pop the plastic light out of it protective rubber case, and press open the back.

      A good light for cycle commuting in cities

      The Knog Frog Strobe light is a bike light designed for riding after dark in well-lit towns and cities. It has a very bright LED which is to enable you to be seen by traffic but will not light the way in front of you on a dark country lane. If you need a light that you can use in these circumstances then it isn't for you.

      I brought this light from Evan's Cycles at £10.99. You can get them from £6.50 Amazon but obviously you have to wait for delivery which isn't ideal if you need to cycle home in the dark straight away!

      It is described as sexy on the packaging which made me laugh as I can't imagine that any would find a bike light sexy!

      The light has four settings, constant, strobe flash, disco strobe, and random strobe. I think that disco strobe is the best to use as in my opinion it is what would stand out more to motorists.

      The light is mounted in stretchy silicon which you wrap around the handle bars (or helmet, seat post etc) to attach it to the bike. This makes it very easy to take on and off which is great as it means you can take it off when you go inside as people sometimes steal lights from bikes. It also means you can position it where you like on the bike which is good for me as I have a basket which means that some lights won't fit.

      The light is powered by two coin cell batteries which, unfortunately, I don't think you can change. However the battery life is 80 hours on strobe so I think that if you buy a new one once it runs out you are still getting very good value for money.

      It is very light 19g so it doesn't add extra weight to the bike.

      The only downside is that the switch is ridiculously sensitive to the point that it seems to switch itself on if you move the air near it. I am not exaggerating I once saw it switch on when I walked past it. This means that if you put it on your bag when you are not using it the chances are it will be switched on all the time and wasting the battery.

      I give this 4 stars it is a great lightweight bike light for city commuting but it would be better if you could change the battery and if it didn't switch itself on so easily.
