You must be traveling, (looking), toward the light source to see it. Otherwise you are seeing your shadow. If you are traveling away from the light you need to be looking back, toward the source. The speed of light is not apparent, only the shift of its color spectrum. When moving toward a light source it appears bluer, away redder.
(Still working)
A light source within your vehicle (or a vehicle following you at the same velocity) would appear normal to you regardless of your velocities (relative to whatever). If you were able to move toward a light source at the speed of light you would burn to a crisp; away from it would simply disappear, (the photons would no longer communicate with you).
Now with all this out of the way, let�s look at how all this would appear to an observer on the ground (so to speak) with a very powerful telescope.

Let�s imagine we send a powerful satellite into orbit around the Earth with a green blinking (once per second) light, and that we are tracking it as it passes overhead in the night sky with a very powerful telescope. This satellite is so powerful that it can maintain its orbit around the Earth at great velocities.
Would anyone care to look at the satellite through this telescope and tell us what you see?

Mib, Clanad, anyone, I still don't get it.
Clanad's quote was something like this:
"Suppose that the speed of light is a hundred miles an hour. You see someone chasing after it in a car at sixty miles an hour. To you, it appears that the light beam is outpacing the car by forty miles an hour. But, the person inside the car must see the beam escaping ahead at a hundred miles an hour, just as one would if one were standing still."
No no no no no no no. If I'm on my bike traveling at 15 mph, and a car passes me traveling at 30 mph, it seems relative to me that the car is crawling along at 15 mph (30 - 15 = 15)
If I'm traveling at 60 mph and a light beam passes me at 100 mph, it would seem to me to be traveling at 40 mph. If I was traveling at 100 mph it would seem to be stationary.
Wouldn't it? And if not, why not? And if you're going to explain why not, please do so again using small words because I am a blinky of little brain.
