Interior 3rd brake light.. are they different for each generation?
 

I'm looking into getting an interior brake light as I am getting a low level spoiler fitted soon, I'm a little curious why they are different prices on subarugenuineparts.com?

I have found one on ebay from a 2013 impreza saloon and from what I can see they all look identical? So can I buy that?
