The quality of light on the High Street will be improved by the use of LED light sources providing a safer environment during the hours of darkness.
The new system will be more reliable and more energy efficient, helping the council meet its energy reduction targets.
With over 2km of underground cabling having been installed, 60 new lighting columns erected and the disconnection and removal of the old equipment, it has been a major undertaking.
Council officers are are working closely with the contractor to manage the project to ensure any disruption to the residents, businesses and visitors of Linlithgow is kept to a minimum.
It should be noted that the works at the entrance to Tesco car park are not part of this project. This was emergency work being undertaken by Scottish Power under temporary traffic management.
Executive councillor for the environment Tom Conn said: "The new lighting columns on Linlithgow High Street are energy efficient and environmentally friendly whilst keeping in with the nature of their surroundings.
"Progress has been slower than was hoped but the difficulties of working in a busy town centre with difficult ground conditions have made it extremely challenging however officers have worked well with the contractor to ensure that the work is completed to a high standard."
