Does anyone know how to get that to be a working brake light again?

And I mean for those of us who have the rear wing. Right now, my rear wing light goes on, but not the one in the window. Is my rear window light just out or is not supposed to come on since I have the wing light?

 

The 3rd brake light in the window is disabled from the factory for cars with the wing since it would look awkward with two 3rd brake lights.
If you want to reconnect it, your dealer should be able to do it for you.
I'm sure someone here knows how to do it too so maybe they can chime in with a DIY.

 

I figured it was disconnected from the factory, but to be honest I'm curious what it would look like with four brake lights. You can never be too safe, right?

 

lol I guess you've got a point there.
If someone doesn't post up on how to reconnect it, then your dealer can definitely do it so just pay them a visit.

 

I recently put on the spoiler, had a family friend who owns a shop put it on. Still have the window light on. It's pretty bright but hey any way to deter people from hitting the G is good in my eyes.
