You must be living under a rock... it's called a rear fog light. It is a JDM feature. And there's a thousand different variations for it aftermarket. Personally the flashing ones (called F1 rear fog light) are so annoying how they flash every single time you brake, but the "4th brake light" idea is de definitely cool.

Well now I feel stupid for not even reading your post guess I should get my coffee before I get on the computer in the morning. Facepalm. Same opinion applies, but haven't seen it on the 3rd brake light before...

I would be interested in something like this (and the same behavior for rear fog) if there was a setting for it that would only flash when the vehicle was at say >60% breaking, or maybe even if there was a proper value that depicts rapid deceleration. This way I wouldn't feel like I'm annoying the guy behind me flashing every time I touch the brake pedal, but it would still add the safety of the flashing in a sudden or hard braking scenario.
