this one?

 

same happend with me, it flashes for like 10 seconds then goes away. i have no clue why.

 

Check for a loose bulb.

 

yeah that picture, but i had my wife press the brake while i looked (hard to check by yourself), and the passenger side brake light is out. price? can i fix it myself (that is can someone tell me how)? or how much at stealership?

 

You can pick up the bulbs at Autozone or Advance Auto for a couple bucks. If I remember corectly... Just pull the carpet down, and unclip the bulb tray on the back of the light housing. Then you can get to the burnt out bulb easily.
