I have been noticing that when I'm driving that the dash lights (along with radio) will suddenly brighten up.
Are they controlled by some light sensor ?
It's not like I am going through a tunnel or something.
Is there a way to 'make' them bright all the time ?

Yes they are on a sensor..I notice it most when stopped under an overpass, or coming out of the garage. I don't know of a way to keep them the same all the time however..

My dealer told me that the light sensor was that little black dome thing on the dash by the windshield. And as far as I am aware, you might try adjusting the headlight dial that sticks out of your steering column - you can turn off the "AUTO" headlights, and turn your headlights on or off by doing that, so I would assume that the dash lights would turn on/off along with that. I don't really feel like going out to my car to verify, but you should try it out, makes sense to me that it would work that way - but then again, it wouldn't be the first time that "what makes sense" isn't what is done...

Do the brighten when it is bright out and dim when it is dim outside? That is way mine work.

I drove under a viaduct when it was sunny - both the dash and head lights both reacted for the two seconds it took do drive under it.

I see this question every year on various forum and various vehicles as the strength of the sun wanes in fall/winter months. When in auto mode the sensor thinks its dark enough to turn on regular lights instead of DRL's, and that includes dash/radio lights. Kind of annoying if you generaly keep the dash lights dimmed at night (can't see them when it switchs in dim daylight).
