Moving the wire around will not change the speed of the electric charge. The lights will always turn on the same time no matter where you've send the photon through. It will be the photon that will turn on the light first. A matter of fact, you can receive a voice message faster by using photon, then by using the convenient way.

If I have a 100 foot long wire that has no slack where movement of the wire turns on a light at the other end and I also can send an electric charge through the wire that will also turn on a light at the other end. Which light would turn on first if I move the wire and also initiate the electrical charge at the same moment.
In other words would the electrical charge be faster than the motion on the wire? Also consider if you used a light photon initiated toward the other end to turn on a light? Would the light or motion win the race?

The speed of sound for longitudinal waves in stiff materials such as metals is sometimes given for "long, thin rods" of the material in question, in which the speed is easier to measure. In rods where their diameter is shorter than a wavelength, the speed of pure longitudinal waves may be simplified and is given by:
This is similar to the expression for shear waves, save that Young's modulus replaces the shear modulus. This speed of sound for longitudinal waves in long, thin rods will always be slightly less than the 3-D, longitudinal wave speed in an isotropic materials, and the ratio of the speeds in the two different types of objects depends on Poisson's ratio for the material.

Entanglement, hands down...provided you can get the entangled atom at the other end to turn the light on.
