The AGLCS system of green light guidance at LGW is a great system safe and must not be scrapped. Already mentioned, it helps you find your way around complicated taxiways at major airports and may well have prevented accidents, had the system been in use in Milan etc. The authorities must not accede to those BA idiots. I believe even Boeing got so fed up with them wanting changes made to their aircaft specifications they were told you will get a standard spec' Boeing.
