CONSTITUTION: A lane for a road comprises a case(11) a solar cell module(12), a condenser(13), a light source(14) and a control device. The case has a space in order to accept the electronic component. The solar cell module is built in the case in order to change solar energy into electric energy. The condenser is built in the case. The electricity is stored in the solar cell module. The light source unites inside the case and emits light.
