What do alternating green/yellow centreline lights along a taxiway mean?

Explanation:
Alternating green and yellow taxiway centerline lights mark the boundary of an ILS sensitive area. They warn you that you’re near the ILS critical area so the ILS signals can’t be interfered with by vehicles or other movement. The proper action is to proceed with caution and follow ATC instructions, and avoid entering or stopping inside the ILS critical area when the ILS is active. This pattern isn’t a sign of a fast turn-off lane, it isn’t about runway proximity in general, and it doesn’t indicate a speed restriction area. It’s specifically about protecting the ILS signals.
