I bought a £17 Cree light off ebay .... I use it in pitch dark cycle paths every night and I only use it on the low setting (it has 3 settings) .... I use the headband and I don't want to 'faff' around with a rubber band every time want to take it off the handlebars
on low, it's superbright like a Volvo bus headlights on bright.... This has been one of my best buys this year...
+1 I bought the older 2 lamp version of this light for super cheap 2-3 years ago. At the price I figured I couldn't go far wrong, and could replace it a number of times if it didn't hold up. Still using it, and if/when it dies, I'll be very happy to buy another.
