You are 100% right. But I can't afford PIAA, especially as the HID kits are ~£300. That's a PC3 or a set of cans, or a new helmet or leathers or....
For £30 I get a HID light setup and should it break, whatever, it's only £30. I'll investigate some bulbs then, instead of a full HID kit.
I will also keep a keen eye out for Chad's trials with the non PIAA kit and see how he get's on. If he still has them in a few months feck it, I'm buying one.
However, in saying all of this...you could have a searchlight taped to the front of your bike, but if it's covered in winter road sh*t, you won't get any light anyway

I don't know how many times I have to clean my headlight through the week before I give it the weekend clean. Pain in the a r s e.
Cheers for the info though.
