Australia's made for day-night Test cricket, according to International Cricket Council president David Morgan who expects it'll become a reality within the next two years.
Trials with a pink ball for use under floodlights are already underway with ICC officials determined to boost global interest levels in Test cricket amid declining attendances for the five-day game.
While Tests remain popular in England and Wales, attendances have dropped elsewhere in the world, including Australia, prompting concerns about the future of cricket's oldest format.
While next summer's Ashes series fixtures have already been finalised as day games, day-night trials at first class level are possible as early as next season, clearing the way for twilight Tests as soon as 2011.
Test cricket's pre-eminence as the ultimate form of the game has come under challenge from the growing popularity of one-day and Twenty20 internationals, especially on the subcontinent.
But Morgan was adamant Tests, in particular big series such as the Ashes, remain the premier form of cricket, both in sporting and commercial terms.
