love a good light thread , the subjects almost worth a forum to itself.
This year Im going minimalist in the lights department, previously I have used everything from the 10/5 watt lead acid recharge every night jobs to cateye sets, torches and headlamps.
I think you can get a cheaper version of the dinotte for £99 but that technology seems to be moving so fast luxeon lights are getting cheaper all the time so Im keeping my money for the time being.
So at the moment I have a couple of "frog" flashing led,s one on the front fork and one on the rear stay They are much brighter than the cateyes, reflect in the spokes and creat a flood of light. I have a very small 1w luxeon which is not much bigger than a single AA to project some forward light.
If Im carry my rucksack that has a cateye led on the back as well and my seat post also has a cateye led as a back up.
The whole lot weighs very little.
Part of my route takes me through woodland and for that I have a petzl headlamp which just because it shines were I look, and is better than any bike light Ive tried, works for me but to be honest I rarely use it nowadays.
