Airport Lighting
RUNWAY EDGE LIGHTS
Single row of white lights bordering each side of runway and lights
identifying the runway threshold
Three Intensity Levels: High Intensity (HIRLs), Medium Intensity runway
lights (MIRLs), and Low intensity runway lights (LIRLs)
Some are Pilot Controlled, some ATC controlled
RUNWAY END IDENTIFIER LIGHTS (REILS)
High intensity white strobe lights placed on each side of the runway to
mark the threshold
RUNWAY LIGHTS
White
TAXIWAY LIGHTS
Blue
2
Runway Edge Lighting
Designed to identify the
edge of the usable runway
surface at night and during
periods of low visibility.
Clear (or white) except the
last 2000’ of a precision or
non-precision
instrument
runway, lights are amber.
3
Taxiway Edge Lighting
Designed to identify
the edge of the usable
taxiway surface at night
and during periods of
low visibility.
Taxiway edge lighting is
blue.
4
Runway Centerline Lighting
Runway Centerline lighting
is used to provide pilots with
alignment guidance during
takeoff
and
landing
operations, primarily during
low visibility conditions.
Runway centerline lights
are white (clear). Except the
last 3000’ portion. 2000’ of
lights
are
alternating
white/red and the last 1000’
are solid red.
5
Taxiway Centerline Lighting
Taxiway
Centerline
lighting is designed to
facilitate
ground
movement,
primarily
during low visibility
conditions.
Taxiway centerline and
lead-on/off lights are
green.
6
Elevated Runway Guard Lights
(Wigwags)
Elevated guard lights
are used to identify the
holding position for a
runway especially at
night and during periods
of low visibility.
Used to enhance the
hold bar and elevated
signs.
7
In –Pavement Guard Lights
Supplement hold bars
and
hold
position
signage to alert pilots or
vehicle operators of the
holding
position,
especially during poor
weather or periods of
low visibility.
8
Runway End Lights
Used to depict the end
of the useable runway to
aircraft.
Arranged in two sets of
four lights.

Runway Lighting
EDGE (WHITE/AMBER)
THRESHOLD (GREEN/RED )
IN-PAVEMENT LIGHTS (17L -35R)
Centerline
Touchdown Zone
10
Taxiway Lights
EDGE (BLUE)
TAXIWAY edges
are indicated by
Blue lights.
11
Airfield Lighting
RUNWAY edges are
indicated by White
lights, followed by
Amber and then Red
as you move closer
to the end of the
runway.

Airport Lighting
AIRPORT BEACON
Used to guide pilots to
lighted airports
Green/White: Civilian

Pulsating Approach Slope Indicator
17
Visual Approach Slope Indicator (VASI)
The VASI is a system of lights on
the side of an airport runway that
provides visual descent guidance
information during the approach to
a runway
View of VASI
