I have seen many examples of the third brake light flashing. I think these are aftermarket add on devices, because I don't think any car out there has this behavior as stock.

The first kind (the most annoying) is the light flashes all the time the brakes are applied.
The second kind is 5 flashes then constant.

It is severely annoying to get behind someone who has this in traffic. I have seen this applied to some commercial vehicles as well.

I am not aware of any laws that prohibit the flashing brake lights but I am not a lawyer or traffic expert.

I thought I read that the newer MBs have the adaptive (on hard deceleration) brake light flashing enabled by default. I went looking around this morning but can't find the reference.

I think the adaptive brake lights are a very good idea. I'm going to look for the setting this afternoon on our W164. The kids drive this vehicle and they have a 2.5 hour trip that is all interstate between home and college.

With all the cheap micro electronic accelerometer technology out there I can't believe someone hasn't come up with an after market device to be retrofit instead of the "blink no matter what" devices.
