An 18-year-old man has been arrested on suspicion of murdering Leonne Weeks, 16, who was found dead on a path in Rotherham.
Glow In The Dark Paths
Starpath - a spray on coating - works by absorbing UV rays during the day and then expelling them at night, creating a blue glow. It gets lighter the darker the night gets.
It will be applied to the main commuter route through William Parnell park in Fulham and will work alongside the existing lighting in the park.
Councillor Nicholas Botterill, H&F Council's leader, said: "It may look like something out of science fiction film but this product has very real benefits.
"As well as improving safety by lighting up one of our less well lit parks, Starpath is environmentally sound, with no ongoing energy costs or light pollution - and it breathes new life into old pathways.
"If Starpath proves popular with park users here it could be rolled out to other under-lit public places in the borough that are a little more off the beaten track."
The Starpath will cost the council about £24,700 to install.
The H&F council says it is expected to reduce annual pathway repair costs significantly as it comes with a seven year warranty, and has the potential to cut the council's carbon footprint.
The finished surface is non-slip and water-resistant, making it ideal for pedestrians or cyclists.
It has recently been trialled in Christ's Pieces park, in Cambridge, where 150 square metres of path were converted and ready for use in less than four hours.
