This is an interesting point. I noticed that at Dublin the new taxi centreline yellow markings are slightly offset from the lights but feel sure that they are on the same line at other airports. Something to look for next time!
I had conjectured that this was so that the nosewheel isn't banging on the centreline lights when one was aligned on the yellow line.
As an aside, do you think it matters if the nosewheel runs over the centreline lights during the take off run or not?
