Best Rear Light?

[mrmr96]

Per title, I need something to make me visible/more safe when riding at night time on the road. What's the best value solution? (Up to say £30)

Thanks

I must admit, I quite like the idea of having two lights. The reason being that if the batteries fail when I'm out then I'm unlikely to notice immediately so would be unlit for a time.

But if I have two sets then when one dies the other will keep going. So when I spot I've one set out I change the batteries in that one (always carry spare batteries) and at least there hasn't been a time when I've been riding unlit, if that makes sense?

Cheers for the link!
