I'm not clear on the question, but remember that lightning is not traveling at the speed of light, nor is it made up of light photons. it is a static electrical discharge which balances the charge differential between the earth and the air. (or the air and the air - cloud to cloud lightning is much more common than cloud to earth). the reason you can see lighting is that as the electrons travel between the areas of different charge, the air molecules in their path (which they use as a road to travel on form one place to the next) become excited by the influx of energy, and emit photons to return to a more stable state of energy.
A lightling bolt hitting a human body is very very dangerous, because lighting is at the one voltage which passes *thorugh* the body, instead of across the surface of it. to be hit by lighting it to have a huge impulse of electrical energy, which will boil your cells, and if you are lucky, not fry your nerves and or stop your heart/brain.
and AFAIK, it is not impossible to travel at or beyond the speed of light, it is just impossible (according to general relativity) to accelarate to the point of lightspeed. If you are created moving fater than light, then you're fine.
