Idea – Does Physical Bodies Emit Invisible Light Dependent On The Velocity?

My idea is simple.

I assume a cooling mechanism in the physical world is emission by light. That is. Energy (light) removal from a body.

A thought experiment would then be that physical bodies emit invisible light dependent on its kinetic energy.

I guess this because if there is a maximum velocity for mass then any energy input that would result in a higher kinetic energy would have to be removed.

The fastest way to remove energy is by light. Hence bodies should be able to emit a kind of light dependent on the velocity.
