Runway end identifier lights, a pair of synchronized flashing lights on each side of a runway threshold, indicate the approach end of a runway.
Stop bar lights are the row of red lights at a holding position where a taxiway meets a runway. When they go dark, accompanied by clearance from ground control, an aircraft may enter the runway.
Noise Abatement 2200—0700 LCL Follow noise abatement procedures between 10:00 p.m. and 7:00 a.m. This may require the pilot to maintain a best-angle-of-climb attitude after takeoff (which puts the aircraft at the highest altitude in the shortest horizontal distance), or a best-rate-of-climb (a gain of the greatest altitude in the least time); in other cases, it may require a takeoff at less-than-maximum power, or refraining from applying full power until the aircraft is, say, 10 miles from the airport. Noise abatement procedures lower the decibel levels for the surrounding community.
MIL/TERM/CARG/RAMP Military, terminal, or cargo ramp (an aircraft parking area, also called an apron) facility is this way.

HS-1 Hold short (do not move until ground control tells you to) of the runway here.
Taxiway Alpha (A) A location sign, which tells you the taxiway or runway you are currently on, has yellow letters on a black square, the opposite of destination and direction signs. Here, Taxiway Alpha continues, angled to the right. Taxiway Charlie (C) runs to the left and right.
