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?MBL87560SEC - 3/13/2005 1:30 PM
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.
