4.0 out of 5 stars Simple and great 13 Mar 2011
By iainecg
Colour Name:Black|Size Name:Rear
First impressions are of simple packaging and design, as with other Knog lights, the size is determined by the batteries (2xAAA) with the unit contained within a one piece silicone moulding. Knog's fitting system using a simple silicone strap is used on the Gekko which enables the lights to be quickly fitted to your bike and be fitted in a number of places. The trio of LEDs are bright and highly visible and the white silicone casing of my model appeared to glow! I stopped on a quiet, unlit road to assess the light's output with my other lights switched off. The light spread is impressive, I had a pool of vision roughly 1 metre either side of me, and a good 5 metres in front, it was fine for a leisurely ride along a quiet lane, when I reached a lit stretch, there seemed to be little light from the Knog adding to the street lighting. I like to have the road ahead lit up in the dark as the street lighting often doesn't highlight potholes and sunken drains, and I'd be reluctant to set out after dark with just the Gekko on my bike. The rear version produces a good output that is clearly visible from a good distance, with a range of flashing options to grab the attention of traffic. Again, I'd be reluctant to rely solely on the Gekko, although that's more down to my preference for multiple lights to maximise visibility than the Gekko's ability. The Gekko is a great value compact light to have in your bag for those days where the light goes early or you end up running late. It will make you visible and gives off enough light for a leisurely ride along an unlit path.

4.0 out of 5 stars Knog Gekko 3 LED rear Light - Black 17 Nov 2010
Colour Name:Black|Size Name:Rear
Bought 2 Gekko's to light up my seatpost. Nice tight fit and unlike the Cateye they replaced, don't catch my inside leg. Certainly bright enough and having 2 means the alternating light show wakes up dozy drivers. Poor water resistance/sealing have been mentioned elsewhere as an issue though I haven't had a problem(don't ride in the rain...!).Price and performance really good so far, hope to be saying the same in 12 months. Silly Swedish humour on the packaging will make you laugh.

Really easy to take on and off. Easy to switch on - even in the rain. Great design. My one criticism is that one of the led lights glows green sometimes!

1.0 out of 5 stars Knog gekko rear light 17 Nov 2013
Have owned this for about 6 months.It was good while it worked properly. Performance became erratic 2 weeks ago (some functions did not work,or only sporadically and the steady 3 L.E.D. would stay lit for 10-15 secs then go out). Now reduced to one brief flash, from one l.e.d. only, when 'on' button is pressed, then.........nothing. 2 sets of new batteries tried, plus cleaning contacts has made no difference. This will be returned for full refund just as soon as I remember where I bought the ******* thing and can find the paperwork!

Full time rider
Part time shopper
One failed within a few dasy got it replaced.
Due to the angle of most seat posts it does not give good visability
For use in a I have lost all other lights only situation.
Cheap construction
Gave them away to someone I didn't like
Would not buy again

2.0 out of 5 stars Fine until wet!
The lights are fine until they get slightly wet and they stop working, have to be dismantled and dried out on the radiator. A real pain. Wouldn't buy again.
