Has anyone successfully installed a 3rd Brake Flasher on their 2008 G37s Coupe?

 

What do you mean 3rd brake flasher? Did you mean 3rd brake light? If so all G's come with a 3rd brake light. Inside the rear shelf if you bought the car without a spoiler, on the spoiler itself if you bought a spoiler. Verts all have them on the spoiler.

Never seen this. Its an animation type thing...? Uh..I don't really recommend it. Its up to you though. It shows that you have to cut a wire so, unless you want to permanently alter your brake lights then don't do it.
