The southern province of Dong Nai has installed 76 traffic lights using solar energy.
Duong Danh Quy, head of the provinces Traffic Safety Committee said the province was the first in the country to use solar panels to supply power for traffic lights.
"During the trial, the traffic lights were as reliable as traffic lights wired to the power supply and constituted a valuable energy saving for Bien Hoa City," he said.
The plan was initiated in 2007 by the committee and piloted in several places around the city.
The solar powered posts have been installed on national highways 1A, 51, 20 in the province and on some city streets.
Quy said the posts have capacity to store enough power for two days operation and they are easy to install, because they require no excavation of the road surface.
The cost for a post is around VND120 million (US$6,282), taken from the committees fund from traffic fines.
Quy said solar powered posts would replace all public grid wired posts in the near future. He called for other provinces to follow Dong Nais model.
