I've had lots of trouble with LED lights before (some losing their connection to the battery, being very dim, generally temperamental) and so decided to go for a headlight style of light. I used these last night for the first time, and compared with my friend's LED front light, this was a lot brighter. It lit up the dark un-lit path in front of me very well, and made me a lot more visible than any other lights I have previously used. The amount of rear light is bigger than expected for its size and it's very bright (the picture makes the rear light seem bigger than it actually is), and the flashing LEDs help with making you more noticeable from behind. The fittings are great, they fit my narrower than normal handlebar, and the rear light fitting is very sturdy. I strongly recommend these lights. I'm looking forward to more night-time cycling!
