OK, it's getting to that time of year where I'm sure we are all thinking of getting our lights out of storage. But I have given my old front light away, as I felt they were too big and heavy. And I'm looking to replce my front with something small and light!! They are only needed as a warning light, as I bike on cycle paths which are lit. So I'm looking for some nice LED's I was thinking of getting the Cateye EL410, but have just come across these, smart LED rechargeables has any one seen these in real life/ used them? How bright are they?
