The alternate possibility involves installing a system of flood lights along the circuit to illuminate it for cars that do not have headlights. The lights must be designed to diffuse light over a large space to reduce glare on both windshields and a driver's visor. Systems such as this have been common in short track motor racing for many years. The night NASCAR race at Bristol Motor Speedway's half-mile track in Tennessee is among the most popular events of the season. The first modern oval track over 1 mile (1.609 kilometers) long to install a lighting system was Charlotte Motor Speedway in 1992. NASCAR sanctioned races have been held at night for many years due to systems like these. MotoGP held its first night race at Losail International Circuit in 2008. Formula One held its first night race at the 2008 Singapore Grand Prix.
