For such a compact light, this magnetic bike lamp packs an illuminating punch. The LED lamp can be set to one of four modes - 100% brightness, 75% brightness, 50% brightness, and a flashing mode that flashes SOS in morse code.  We think the best feature of the lamp is the magnetic grip. The mechanism means the lamp can be attached to nearly anything - your bike frame, your clothing, the strap of your helmet, or your bag. It means even if you're not on your bike, you'll still find the light useful.  The lamp is rechargeable by USB, and comes with a quick-charge-enabled charging cable.
