I've had my SVT for less than a week, so I have no idea if the fuse / fuse box diagram is in the manual or not--check that first to find out if there's a specific fuse for the guage cluster lighting. Usually, it's all tied together, so just one thing wouldn't go out. Hard to believe a bulb of some sort would be done already, but I guess that's a possibility.
And of course, you're within warranty, and this is probably covered, so I'd just stop by a dealership for a fix. In the meantime, take care with the night driving, eh?
