SPOILER ALERT
This one actually has a really satisfying solution.
When you start you don't know if they're both on, both off or one on, one off.
So first thing you do is click 'I'm feeling lucky.
If they spin, you know they aren't both on, or you'd get the question right.
So now you flip both and try again. if that doesn't work you know they must be one on one off.
So now you flip one of the toggles and click again. Either you picked the right one and they're now both on and you get the question right
or you get the wrong one and they must now both be off.
So now you flip them both and hit 'feeling lucky'.

ah ok
I think the bit that wasn't obvious was that 'I'm feeling lucky' was also the button to press to check your answer
