I have just bought my dream car a 2010 camaro ss and the last few days i noticed that one of the break lights is on when i turn of the car and take the key out. The light turns off if i pump the break a few times. Do you guys have any idea how i or a mechanic can fix this

?
Here is a picture of what it looks like when the car is off:
