Bike-Lighter / Solar energy light

When we ride the bicycle at the mid-night, very easily hitting the other people.Though on
the wheel of our bicycle there\'s one reflection plank so as to avoide accidents at night.
it still has a lot of problems.

This desigen replace the reflection plank with a small solar energy light.It can absorb the
sun light energy to combine the conversion the electric power on daytime when we ride our
bicyle.In the evening , it will give out light from the LED-lingt since you start to move.
Thus there will be two brighe wreaths.

Not only it will attain a more interesting result, but also can remind the other people of your riding.
