Yes, I do believe that there was a dial in that same general area on the '12 that I test-drove. I didn't mess around with it at all though. Can you give me an idea of the range of intensity that dial allows you to toggle between? I'm not completely opposed to keeping the stock red color as long as it's not bothersome.
The circle is where I think that dimmer switch is on the '12 & '13 Imprezas.
The arrow is where I'll get the fog light button, since I added them as an option, it's there, not on the turn signal stalk.
