So, the sis is getting a new bike fro Christmas (or so Dad says) having had hers nicked this year. She'll only really be using it for riding on tarmac, and at that mostly in built-up areas. She's in need on some lights for £20 or less, what would you go for?
I was thinking one of these up front: http://www.wheelies.co.uk/p15508/Electron-Nano-9-LED-Front-Light.aspx?utm_source=googleps
And then some generic cheapo light for the rear (they never seem to last long, however much you spend).
