Brake light comes on when shifting?

Hey guys. I have a 99 coupe. The brake light indicator is coming on when I shift. Only when I shift. It turns off after the shift. The only light ive seen when shifting before is the traction conrol cause i was rippin! Happens Id say 70 percent of the time. The brakes feel ok. I just got it two months ago. They put new pads and rotors on when I bought it (dealership).

Any ideas? Or what to look for?

Thanks!
