It's hardly a Mercedes "innovation" since the original work and "biomechanical" tests were done decades ago on taxis and motorcyles . . . leading to the sale of Hyperlites since the early 1970's

Didn't lots of japanese cars come with these a few years back and then they all but went away?

I remember reading about the DOT studing this 10-12 yrs ago. The idea was to vary the frequency of the "off" pulses based on the decel rate of the vehicle. At rest and normal decel rate, no off pulses; hard braking=double turn signal rate; panic braking=faster rate. Guess it finally got off someone's desk.

Regardless of when the concept was first developed, it's nice to see it finally implemented. As far as the annoyance of the flashing lights is concerned, if they only flash under emergency braking then it shouldn't be an issue.
I guess we just wait and see if it actually takes off.

Some Audis have brake lights that are brighter the harder you brake. doesnt really prevent rear-endings, but it'll alert people behind you if you're braking really hard.

You & MTI are correct. The product tested was the Voevodsky Cyberlite. Tests in the '70s using Checker taxicabs fitted with the C/lite showed a 300% reduction in rear end accidents when compared with the control group w/out the additional lamp.

It had an accelerometer to measure how hard the vehicle was braked. Sitting at a light - brake ON, the unit flashed 1/sec. and would vary the flash rate up to 7 flashes per second if the brakes were hit really hard. It also had a photocell to measure ambient light in order to dim the pulses at night so as not to aggravate following drivers.

I had one on the back of my motorcycle from '81 through '94, when I sold my K100RS. I gotta tell you, I felt much more secure giving an active feedback message to following motorists while using the brakes. This was in the good ol' "B4 cellphone & SUV" days.

I think an active brake light technology is a good idea. Obviously, not a replacement for good driving & road manners, but to get the following drivers' attention.... especially today. Good for MB and some of the other more progressive manufacturers.

That's really clever, especially the photocell used to dim the lights at night. Do you know of any current aftermarket manufacturers of active brakelights like that?

Flashing brake lights,... i think MB/DC is running short of ideas.

I heard that the current 7 has taillights that get brighter with the amount of force applied ot the brake (but only when in D). Not too sure but I heard that is also soon to be the case with the new mercs (facelifts included).
