How can you see where the nosewheel is in relation to the centre line, or is it just practice? I know that on the A380 there are cameras available in the cockpit so that pilots can see the position of the gear (nose and main) relative to their surroundings.

With regards to airport lighting, when I took of from Seoul I was able to see that the taxi way immediately adjacent to the runway (where we were headed) had a line of lights halfway up it indicating our hold position until we were given clearance. Once we had been given our clearance (I assume), the taxi way lit up and we proceeded to the runway. Is this normal? I don't remember seeing this at any other airport.
