Bahrain has confirmed that next year's Formula 1 grand prix will be a night race, as AUTOSPORT revealed in September.
The ambitious plans are part of an effort by the kingdom to celebrate the 10th anniversary of its inaugural F1 race.
Floodlights have already been installed at the Sakhir circuit and are being given their first trial at this weekend's World Endurance Championship event (pictured).
Bahrain track boss Sheikh Salman bin Isa Al-Khalifa said: "We are delighted to be able to trial the first phase of our lighting project at the WEC, a major milestone in this hugely ambitious project for the BIC, which is scheduled for completion in February.
"This is by far the biggest development project we have ever undertaken at the BIC since the circuit was first built.
"I believe that there can be no better way for us to mark our 10th anniversary in F1 by demonstrating our long term commitment to the sport through this significant investment."
Bahrain GP organisers have also promised upgrades to the spectator facilities at the track, as well as light shows to enhance the spectacle of the night race.
