EDIT - Oh, and my Aldi "totally the same as the Moon Nebula" light packed up at some point during the ride. I normally run two lights if they are needed but as it was daylight I didn't 'need' a light so just relied on that one. I only had it on low flashing and it had plenty of charge but it seems that the cool weather sucked the life out of it. It has now been relegated to backup light and will be further relegated to the bin when I find what I want to replace it. Why won't someone make a rechargeable light with about 25 Lumens that has flash and steady, that's it? I don't want 10 levels of output, sixteen flashing modes and a super powerful retina destroying setting that kills the battery in 3 minutes. Maybe I should design my own, I'd even throw in a feature where it beeps when it goes on so you can reach around and click it on while on the move and know, even with gloves on, if you've actualy switched the thing on. Quick, to Kickstarter!
I bought a pair of these:
Bicycle Bike 3 LED 4 Modes Head Front Rear Tail Light Lamp USB Rechargeable
Just over £7 all in for both, and they've been excellent so far. The front is obviously just a "be seen" light, but I have two other powerful lights for dark night riding.
