Kevin Sheedy has urged the AFL to be brave and at least trial a twilight Grand Final.

Inspired by the success of the pink ball day-night Test match in Adelaide, Sheedy - the driving force behind the Anzac Day and Dreamtime at the 'G blockbusters, and next season's Country game - says the League could reap huge benefits from the bold move.

"If they want to vote, I'd put my feet and my hands in the air to have a twilight grand final," Sheedy told SEN on Wednesday.

"Have a look at it because at least then you've had a look. We've done over a hundred years of (day) Grand Finals and we won't look at something different.

"It might be pretty good - it might be better ... we don't know unless you actually try.

"At least cricket has had the courage to go and try it - I thought it was quite successful."
