The pink ball concept excites Nathan Lyon but the Test spinner says he doesn't want to see day-night "overkill".
Australia will line up for their second straight pink-ball Test, a three-match series opener against Pakistan starting in Brisbane on Thursday.
Lyon has only fond memories of Australia's two day-night Tests on home soil - he's played a key role in winning both.
And he's expected to again be a factor in this week's pink-ball clash with Pakistan on a bouncy Gabba deck.
However, Lyon hoped the concept remained a novelty in the game, not the norm.
"I don't think we need to overkill it," he said of day-night Tests.
"It's been a great success down in Adelaide but I think it's quite important we leave Test cricket still a traditional game.
"I know the game's moving forward but I'm a big believer in trying to keep Test match cricket as traditional as possible, with the odd pink-ball game.
"I'd hate to see a five-Test match Ashes series next year all pink ball."
Up to two day-night matches were initially mooted for next summer's Ashes series.
Cricket Australia are set to confirm the 2017-18 Ashes dates before the clash with Pakistan.
Adelaide looks set to host a day-night clash if included in the Ashes schedule following the success of the third Test between Australia and South Africa.
Almost 126,000 people attended in four days to see the hosts thump the Proteas by seven wickets.
This week's series opener against Pakistan marks Brisbane's first pink-ball Test.
Lyon played in the day-night Shield game for NSW at the Gabba in October and said the ball still needed work.
"I do like the concept," Lyon said.
"I think the ball has improved from last year but I think there is still room for improvement there and I know Kookaburra is working hard on that."
Since the pink ball's Test debut in Adelaide last summer, it's kept the black seam for visibility but has a thicker lacquer covering to ensure it retains its shine for longer.
