The 2014 Bahrain Grand Prix has been switched to a night race as organisers mark the tenth anniversary of the circuit joining the Formula One calendar.
Bahrain will join Singapore as the second night race on the calendar on April 6 when the race will be held under a specially-designed lighting system around the 5.4km track.
"This is by far the biggest development project we have ever undertaken at the BIC since the circuit was first built," said Sheikh Salman bin Isa Al-Khalifa, Chief Executive of the Bahrain International Circuit.
"I believe that there can be no better way for us to mark our tenth anniversary in F1 by demonstrating our long term commitment to the sport through this significant investment, cementing our place as the home of motorsport in the Middle East."
Qualifying and the race will start at 6pm local time - 3pm GMT - while drivers will get their first taste of the track under lights during practice ahead of qualifying.
The circuit will now have 495 lighting poles, 450 light fittings and over 500km of cabling.
