Then why use your own (sloppy) definition instead of the standard one? For example, you forgot to specify the medium this light pulse is traveling in. And why make it a light pulse, when just "light" is sufficient? So... it's the proper frame? Why not just call it that then? Why invent confusing and non-standard terminology? Why go through all that trouble to, in a cumbersome way, define something that's already well established?
