My parents as a present gave me a new bike headlight for my bike commutes. It's the Cygolite Expilion 700. I charged it up last night and used it this morning on my ride into work. I used it on the "day flash" mode as it was already bright out. I was impressed. The flashes were strong enough to light up signs 50 yards away in broad daylight. I'm curios to use it tonight when it's dark out.
