There's two different questions here.
Can you cross a red when taxying, if the condition has been fulfilled?
and
Can you cross a red to line-up at the full length when the condition has started it's take-off roll?
At LL when under the supervision of the ground controller we have lighting operators who work with with us, by monitoring the fequency and formulating plans, these guys do a difficult job as they have no flight progress strips to reference. So it happens at times they may forget to drop a red after your condition has passed, a quick call on the RT will never hurt, no matter how busy
you think the frequency is. At least then we have no ambiguity.
When you're in the queue for departure (these runway holding area lights are controlled by the actual departures controller) If he/she is doing the job properly as soon as the your condition aircraft is on the runway the lights should be changed to give you a green route, thus leaving you with task of lining up when you are comfortable, if that's nose to exhaust it's up to you. NB this obviousley doesn't apply to intersections.
As for actually crossing a red anywhere on the airfield, there's no excuse, unless it's u/s. Even then that's a big grey area. I wouldn't worry though as far as LL is concerned, there's gonna come a time not soon when no-one can taxi anywhere if HAL keep closing down parts of the airfield for yet more work in progress....... but that's another thread.
