Tail Light Question

Hey all,

I have a 2005 RX-8. I got pulled over recently for my tail lights being out. I checked and only the two little red lights on the sides are on. The big red circles still light up though when I press my brakes. So I'm confused if:

1) The tail lights are supposed to be that way, just the little lights on the side
2) Something is wrong with the bulbs, wiring, etc.

Can anyone confirm for sure? If #2, any idea what might be wrong?

Thanks in advance!
