File under coolest bike light ever.
The Revolights use 24 LED lights per wheel, 12 on each side, with the front or rear facing bulbs turned on to create the illusion of partially light wheels. The system’s comprised of circular mounts for 700c and 27″ rims and a hub mounted battery pack with frame mounted magnets. Using an accelerometer and the magnet, it senses where the wheel is in its rotation and lights the front or rear eight (four on each side) LEDs.
In addition to looking killer from the side, they actually provide 360º illumination. The bulbs are set slightly back from the inside rim and project light both sideways and to the front (or rear) of the wheel, letting you use them to see where you’re going and letting people see you from behind and the side.

Revolights are designed to withstand the elements and reasonably cold temps, but they do warn against excessive exposure to road salt and other de-icing chemicals. With eight bulbs turned on, they pump out 35 lumens per LED for a total output per wheel of 280 lumens, pretty decent for getting around town.
Retail is $250. System weight is 12.3oz (348g). Battery packs are USB rechargeable and good for four hours of light per charge.
