I admit I haven't ridden with them yet as I just bought my bike yesterday, but these look like very nice lights. Absolutely feel the tailight is among the brightest I've seen. The headlight has no directional beam so I don't expect that to be great as a pure headlight. I intend to use that more flashing to be seen during night rides.

If you have experience with these, please post your thoughts and tips.

If it's actually 90 lumens, it's a weakling compared to the 500+ lumens from a Magicshine clone on amazon for $35.

Having seen just about every product video on the Serfas site, I'd concur that the front one is best suited for 'see me' duty.
