In the research that resulted in the high mounted 3rd brake light, several
different brake/running/turn light combinations were studied. The 3rd
light showed the most significant reduction of read-end accidents, but
providing seperate brake, running, & turn light also significantly reduced
rear-end accidents.
Perceptually, the probablity of visual detection of a light going from
"off" to "max illumination" (brake light) is higher than going from "lower
illumination" (running light) to "max illumination" (brake light).
Therefore, if one wanted to increase the probablity that the person in a
the car behind you would see your brake lights illuminating, Bob's second
suggestion (brake light only) theoretically would be the better one.
Class dismissed... ;-)
