Harbour Bridge, one of Australia's best known and most photographed landmarks, has been incorporated into the annual Vivid Sydney light festival, which draws thousands of interstate and international visitors.

Featuring more than 100,000 individually programmable LED lights, visitors to Luna Park on Sydney's north shore can control the colours on the western side of the bridge with a bespoke colour pallet between 6pm and midnight each night until June 10.

The ambitious project has been coordinated by lighting designer Iain Reed, who lit Sydney's tallest buildings for Skyscraper Illuminati as part of Vivid 2011.

"The Bridge is such an amazingly beautiful structure both from the outside and inside," says Reed. "I wanted people to have the chance to play with its appearance, to turn it into a kind of fairy tale."

Reed and his crew of ten worked through the night for weeks to install the lights and hundreds of kilometres of cable to power them.

More than 60 different light installations are featured in Vivid Sydney, including projections on the Opera House, a Doctor Who special on Customs House and a light walk from Circular Quay to Darling Harbour, where viewers can watch an incredible laser light show.
