For all waves (light waves included), the moving observer and the stationary observer see the same wavelength:

University of Texas: "Thus, the moving observer sees a wave possessing the same wavelength (...) but a different frequency (...) to that seen by the stationary observer. This phenomenon is known as the Doppler effect."

This means that the speed of the light waves relative to the observer varies with the speed of the observer, in violation of special relativity.

Einsteinians hate this conclusion and claim that, for all waves, the moving observer sees a wavelength different to that seen by the stationary observer, Divine Einstein, yes we all believe in relativity, relativity, relativity:

"The observer moves closer to the source. The wave received has a shorter wavelength (higher frequency) than that emitted by the source. The observer moves away from the source. The wave received has a longer wavelength (lower frequency) than that emitted by the source."
