Let's assume that we accept your postulated interpretation of the color of a traffic light and its intended effect being relative to the wavelength of light corresponding to the shown color. I will also assume that you made an error in your stated units (m/s), which would be of velocity rather than acceleration (m/s^2), and that acceleration is the intended effect. What colors (expressed in wavelength) would be shown for the intended effects of:

a. Positive acceleration equal to an object's acceleration due to earth's gravity (on the planet's surface - i.e. 1g).
b. Negative acceleration such that a vehicle travelling at 50 mph would come to a complete halt within 10m. 
c. Positive acceleration equivalent to that experienced by an object at the event horizon of the largest known black hole.

Moreover, if you consider the relativistic doppler effect, how should the traffic light adjust the light output such that an observer obeying the intended effect actually sees the correct color of light?
