ECO-FRIENDLY street lights are being installed across Kirklees.
Old concrete lamp-posts with yellow lights are being replaced by modern steel posts with energy-efficient white bulbs.
They use half the energy of old sodium lights.
Kirklees Council hopes the brighter light will deter people from committing crime on the streets.
Around 10,000 of Kirklees' 50,000 street lights are set to be replaced under the scheme, which is being funded from the council's capital replacements budget.
The work will take 10 years - at a cost of £600,000 a year.
So far, 2,200 street lights have been replaced.
Priority has been given to installing new lights where old ones were run down and needed repair.
The latest area to benefit from the new street lights is Cleckheaton.
Lights have been replaced on Carlton Way, Clarence Street, Crown Street, Milton Terrace, Pearson Street, Quaker Lane and Vine Street.
Some lamp-posts have also been re- positioned to give better dispersal of light.
Clr Ann Raistrick, Kirklees Council ward member for Cleckheaton, said the new lamp-posts have been well-received.
She said: "Street lighting is an important issue. Consideration is being given to the placement of the posts to ensure that the light is effective.
"This will help improve road safety, while acting as a deterrent to troublemakers and criminals.
"From an environmental point of view, they are much better and it will be a big saving in fuel."
