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."

That is, the observer moving towards the light source with speed v measures the frequency to be:

f' = f(1+v/c) = (c+v)/L = c'/L

where f=c/L is the frequency measured by the stationary observer, L is the wavelength, and c'=c+v is the speed of the light waves relative to the moving observer.

Clearly the Doppler effect topples Einstein's relativity.
Look at it this way: (You said)
f' = f(1+v/c) = (c+v)/L = also, factored,
= c/L + v/L = f + v [m/s]/L [m/cycle]
The last term, v/L, is the local increase in frequency, which you can
make yourself by rushing toward the light.
It is the product of speed meters/second, with the wavenumber,
1(cycle)/L meters.
When you separate it like that you can believe it and understand it,
but that doesn't mean you can bundle it up as the sum of speeds c + v.
