Could have it installed on my used Honda mini van by a VW dealer couple yrs ago.  I mean the wife's mini van.

   Safety, but I did not buy it, literally.  Can you imagine the sensory overload if all cars have it at night, in rain,6 lanes traffic??

Flashing RED lights are against the law ( for public) in a lot of States.

Courts are now accepting Dash Cam footage, lawyers are eating it up and now the truth of idiot drivers NOT the one behind them is coming to light.  Not ALL rear end collisions are Rear Auto's fault.

I'll clarify this for those that are having trouble comprehending this issue.

  

  Before I retired I was the senior driver at the company I was at, this put me in the position to deal with driver incidents. This particular incident I mentioned never went to court. The accident report that was written by the officer doing the initial on scene investigation (who reviewed our drivers dashcam at the scene) stated the the BMW driver was the major cause of the accident, therefore our driver was not charged. During the following investigations done by both insurance companies, it was determined that the BMW driver braked hard enough to activate the ABS brakes, This was confirmed by the datalogger in the BMW. The dashcam from our truck showed that there was not any reason for attempting to stop at the intersection that had the overhead flashing yellow lights. there were no other vehicles in front of the BMW or attempting to enter from either side.  Therefor the BMWs insurance company dropped its claim toward Our insurance company.

 A dashcam saved our driver and our insurance company quite a bit of trouble. No matter what the BMW tried to say afterward, the Dashcam was what carried the weight of truth.

It is also illegal to run many of these super bright LED lights on the highway. You can have them mounted for off-road use, but can't run them on the road.

You don't say!  You mean things change?  Wow, never would have thought.

Yes.  And HISTORICALLY, been very difficult to prove that the lead driver slammed on his brakes "too much".  Hence, nearly 100% at fault as you said.  This will be sliced and diced and disseminated to the umpteenth degree in the coming years.  Like other telemetry needed as the other side pushes back.  How much delay between the lead brake lights coming on and trailing vehicle brakes applied?  Speed of trailing driver? Condition of brakes, tires, braking forces. Ahhhh.....love perpetual arguments.  

It'd be nice if LED brake /tail lights were mandatory.

They come on a LOT faster and can give the guy behind a wee bit more of time to react, providing he's not yapping on his phone, selecting toons or having a bowl of wheaties behind the wheel...

 FYI, There is a flasher module available thru motorcycle aftermarket parts venders that quickly flashes brake lights 3 - 5 times then solid another that continuously flashes rapidly until release brakes. They should be able to go on a car or pickup fairly easy. The LED tailights don't draw many amps.
