London Mayor has recently announced that Transport for London (TfL) is to spend £2.4million to replace 3,500 existing lamps at some 300 junctions in the city with energy-efficient light-emitting diodes (LEDs).

According to TfL, LEDs consume 60 percent less electricity and thus generate far less carbon dioxide emissions. The 300 new LED-fitted junctions are expected to save about 600 tonnes of carbon dioxide emissions a year and lower energy costs by an estimated £200,000.

This introduction of LED traffic lights is the largest of its kind in the UK. TfL is seeking to stimulate the development of LED traffic signals and to encourage more manufacturers to join the market.

As part of Mayor Boris Johnson’s efforts to reduce 60% of the city’s CO2 emissions by 2025, the switch to LED traffic lights follows the introduction of LED lighting at all London Buses roadside ticket machines and LED lighting at 3,500 solar-powered bus stops and 640 shelters. TfL hopes the initiation will pave the way for the wider introduction of LED across the country.

TfL has issued a notice seeking companies to supply and fit the lights, with the application period closing on 24 August. The scheme is being funded through TfL’s Climate Change Fund.
