To be honest, a cheap light is a cheap light.. but I have had my rear light stolen before now and had to cycle home in the dark without one (in truth, it was like 1 am and I went via the back roads but I still felt very exposed and pulled off when a car approached). I currently have a rear pannier frame which has a built in reflector and have thought it would be useful for that to be a light, though I can't charge batteries on the bike so they need to be removeable easily. I'm nervous about leaving anything on the bike that is easily removable though.. so a small light is enough. The LED ones these days easily fit in my pocket and are way bright enough for city riding where all you need is visibility. I'm intrigued about that chain drive though..
