I'm going to be looking to increase my lighting in time for fall riding. Right now, I've got a 400L on the head and 600L on the bars. I really won't need this again until Labor Day - here in MN it's light until really late (9pm or so). But, after that, I'll need more light for high speed road riding.

Anyone have any insights into what we will see in time for fall? Or do I buy now stuff on sale (Dinotte 800L for example).
