25
RWY Guard Lights
* Installed at taxiway/runway intersections
* Pair of elevated flashing yellow lights on either side of TWY
Or,
* A row of in-pavement yellow lights across TWY at the runway holding position marking

26
Stop Bar Lights
* Confirm the ATC clearance to enter or cross the active RWY
* A row of red, unidirectional, steady in-pavement lights across TWY at RWY holding position, and elevated steady-burning red lights on each side

27
Enhanced Centerline
* Parallel line of yellow dashes on either side of the normal TWY centerline
* Enhanced for a maximum of 150' prior to a runway holding position marking
* Warn pilot of approaching a RWY hold position marking
28
Code Beacons
* ID airports and landmarks
* Flashes the 3-4 character airport ID in Morse Code 6-8 times per minute
* Land airports flash green
* Water airports flash yellow
29
Aviation Red Obstruction Lights
* Flashing red beacons (20-40 flashes per minute) and steady red lights during night ops
* Orange and white paint is used for daytime marking
30
Medium Intensity Flashing White Obstruction Lights
* Daytime/Twilight
* Reduced intensity for night ops
* Not normally installed on structures less than 200' AGL
* When used on structures 500' AGL or less, other methods of marking and lighting may be omitted
* Orange and white paint required on structures 500' AGL or more for daytime ops
