Halfords sell those wrap around lights.

Isn't there like a legal brightness that lights have to be though?

Those wrap around lights don't look very bright at all.

Rear lights are pritty hard since most people dont have a seat post

I've got one that's elastic and it goes around my seat stay so it's all good

Anyway yeah there are stupid laws like certain light (flashin) you have to use it with a stationary one!!

From my favourite link:

Bikes ridden at night need front and rear lights, flashing or steady.

At night a bicycle must also be fitted with a red rear reflector (and amber pedal reflectors, if manufactured after 1/10/85).

In Manchester, there's so many scallies riding around with no lights or brakes (V-brakes unclipped because the wheel is f**ked) that the police turn a blind eye to most things, I ride my bike without lights and no one cares. But then again it's not very safe, so I use them when I remember. Driving a car you know how invisible cyclists can be.
