Nice idea looks neat and well made, but im a ruck sack wear'er too. So that puts pay to that. Also white LEDs? Most people will probaly only look for amber if they are even looking. I did have a stab at doing something along the same lines which i put
here
I also saw a while back someone inventing a
coat with LED arm signals and LED's to show if you are slowing down. Clever but two floors. The arm indicators in the sleeve were too heavy and slipped down to under the arm and a lot of cyclists wear a rucksack so you wouldnt see the brake indicator.
Saw a
watch version too but the youtube videos didnt impress me much. The follow on from this was LED's in a glove which seemed better but too small for my liking.
These mounted indicators look pretty good for commuters too. But from reviews i saw they we're entirely waterproof and people suggested waiting for the next upgrade to the product. I have no idea if this is even planned. I was pretty tempted to get a set to look at. Maybe they could be waterproofed easily im not sure.
I think a major thing is image. Whilst i dont mind wearing my LED arm sleeves with the LEDs on, i dont imagine everyone will. The same with the lights from bicygnal. Ive actually seen someone commuting with these, but before i could stop them they had passed me.
