Okay I get what you're saying now...BUT who, and how, did someone come to the conclusion that the leading observer would see a redshift as opposed to a light approaching slowly?
It seems that i just cannot get to my computwer in time. this time i fell ill and had to spend two days in hospital. Thank God for antibiotics!
Accordng to the trailing observer (who is under the impression that he is stationary) the leading observer is moving away from him. Vice versa, according to the leading observer (who is under the impression that HE is stationary) the trailing observer is moving away from him in the opposite direction. Both observers measure the SAME light speed and the same speed v with which each is moving away from the other. Therefore both observe a redshift in the light emanating from the other observer.
