Some very cool lights available at Reelight and developed in Denmark, a country that knows what bicycling is all about.
* The LEDs blink as you peddle, when magnets pass the light mounted on you bike wheel
* No need for batteries
* No maintenance of the lights
* No moving parts in the system and therefore long durability of lights and magnets
* No need to be concerned about forgetting them as they are fixed on the bicycle
