Second Generation One-Piece Design LED lighting system with USB rechargeable Quick Release battery for multi-purpose users. Cygolites Expilion takes one piece lighting to another level, giving riders a light that is small for daily commuting and bright on the trails. New for 2011, the ExpiliOn 250 is Cygolites brightest and lightest one piece lighting system featuring 250 lumens of intense LED light seen through 6 different lighting modes, and powered by a Quick Release USB rechargeable Li-Ion battery. At only 130 grams, this light can be mounted with the included handlebar or helmet mounts to light your favorite commute or trail.
Weaknesses: Charge port cover is a bit hard to close.
This light is compact, bright, and easy to use. Cygolite sent it to me as a warranty replacement for my Milion light after the mount broke, despite the fact that the Milion broke 3 months after the warranty expired. The attachment point for the handlebar mount on the Expilion looks different from the Milion mount, so Cygolite appears to have addressed a design flaw in the Milion.
