Power saving is on the highest priority of countries, that is why now a system has been developed to save power in small towns. The use of this new system is very easy and requires no big skill. Moreover each individual has a control to save some light for his/her hometown. The technology is simple, the street lights in a town takes a lot of power because they have to be switched on all night, but what if the town has a low number of people and not many people walk in the night. All one have to do is use a mobile service which will switch on the street lights for 15 minutes. The technology has been named Dial4Light.
