Last week I had to go to work before it got light. I set off with my Argos commuter light attached, and it soon became apparent that, although it makes me visible to other road users, I can't actually see very far ahead. Having been on many defensive driving courses and such, I'm used to looking at the horizon while I'm on the road. It's most unnerving pottering about on an unlit road like someone who's lost a contact lens. And I'm concerned for the rabbits. I like the idea of dynamo lights - but are they bright, and do they cause major drag? And if that's a non-starter, are there any good super-bright lights that run off a rechargeable battery pack that can be bought on a sub-£50 budget for front and rear?
