Yes, they are back lit just like the radio and heater controls. Well they are on our 2010 Si.
I had one go in our old 2004 Jazz. Small bulb. Reasonably easy to replace but there is quite a bit of work to get access to it. From memory I think you have to take the radio out.
What's odd is for all of them not to be working. Can't believe all of them have blown unless it is a different arrangement in the 09-15 Jazz.
