FRONT LIGHTING.
OK - I'm going to link to this from all over the place, because this is my Definitive Guide to Front Lights.
USE A DYNO-WHEEL AND SOME KIND OF GERMAN LED LIGHT.
Er... Just that, really.
I don't want to hear anyone saying "What about Battery lights?" or some such bollocks. They are SHIT!!! OK? Fucking SHIT!
I have (*counts*) Two Hope One front lights, (even more counting) One hundred and thirteen thousand AA batteries (or 24 - still quite a lot), and four (yes FUCKING FOUR) battery chargers.
Now.
Chris. How many times, in the last five years, and (counts some more) 78,453km of cycling, have you had a problem with the dynohub/LED combo? Erm... none. Not once. Never. Nada. Turn it on - there it is.
Even in the rain, Chris? Yep - rain, fog, snow, freezing fog or just because I forgot to turn 'em off. They're ON.
I see.
Chris. How many times have you had a problem with your battery lights?
Erm. Pretty much every time. They last about 15 minutes, then I have to change the batteries and they last for another 20 minutes or so before cutting out.
Now folks. I'm prepared to accept that when it gets dark around here, it gets Properly Fucking Dark. None of that Orange Sodium Glow shit. It's Dark. You get it? There could be a 6 foot deep chasm in the road - you wouldn't see it - you'd ride into it and die. It's fucking dark. So you need decent lights. But my battery lights just don't seem to last more than about 20 minutes.
So. Now that it's Autumn, do yourself a favour. Unless you live in (a) London, (3) Manchester, (vii) Leeds or (finally) Birmingham, forget that family meal at Bargain Burgers & Grill - buy yourself a dyno-hub wheel and light, and throw your Hope Ones in the bin. They are Complete Shit.
