I had noticed the park light switch. Never bothered to try it in all honesty. I was watching a couple of JDM STI's though and I noticed that all 3 brake lights (in the tail light housing) light up, in addition to any parcel shelf light.

Wasn't sure if this was something that anyone had looked into or if the tail lights I saw were a one off of sorts.

I did see an STI the other day with all 3 tail brake lights lighting up. Perhaps I was tired and seeing things though..
