Kimi Raikkonen can be added to the list of drivers who are fans of the Halo after it had an unexpected benefit at the season-opening race at Albert Park.
Due to the late start time of 16:10 local time and a sunset of 19:26, the sun is low on the horizion during the latter stage of the race and the glare can be distracting to drivers.
However Raikkonen says the Halo acted like a sun visor and therefore had an added and unexpected benefit in Australia.
"It was no different than in testing or at any other point and I think it definitely doesn't disturb you at all," said the Finn, who finished third at the weekend.

"I think it was helpful here because of the sun; when it's coming in at the right height, it's blocking the sun in the eyes."
"So, I think it was beneficial here, and it's safer. Maybe people don't like how it looks but you know, it might make a difference for us one day and it's a good thing to have."
Ferrari team-mate Sebastian Vettel agreed, though revealed one drawback of the reduced upwards visibility.
"During the race, it was no issue. As Kimi said, it even helped [but] in the parade lap, that's when it was bothering me because you couldn't see so well the people in the grandstands."
