Product Overview
Runway Guard Light
What It Is
Runway Guard Lights (RGLs) provide an enhanced visual warning at runway/taxiway intersections and runway holding positions, identifying where aircraft and vehicle operators must exercise particular caution before entering or crossing a runway.
An RGL supplements the holding-position environment and works with stop bars, taxiway centreline and edge lights, runway edge lights, holding-position markings and airport lighting control systems.
Selected According To
- Runway/taxiway intersection and holding-position arrangement
- Taxiway width and centreline lighting
- Stop-bar installation
- Low-visibility operating requirements
- Elevated or inset configuration
- Optical direction and flashing/alternating operation
- Light intensity and series-circuit requirements
- Mounting and control-system requirements
- Project technical specification
The final configuration should follow the approved airport lighting layout, applicable aerodrome standard and operational control philosophy.

Function
An Enhanced Visual Warning
Role of the RGL
The RGL provides an enhanced visual warning at a runway access point. It does not replace the holding-position marking or a stop bar where one is required — it adds a conspicuous cue when approaching a runway.
The Safety Function Depends On
- Light colour and alternating operation
- Optical direction
- Fixture location and spacing
- Visibility and holding-position geometry
- Stop-bar and taxiway-centreline coordination
- Electrical circuit integrity
- Control-system operation
- Maintenance condition
Yellow Warning Indication
Alternately Illuminated Yellow Lights
Yellow Warning Lights
FAA AC 150/5340-30J describes elevated RGLs as two alternately illuminated, unidirectional yellow lights, and in-pavement RGLs as a row of alternately illuminated, unidirectional yellow lights.
Alternating Operation
An RGL is not simply a steady yellow light. The alternating illumination increases conspicuity and distinguishes the RGL from steady-burning taxiway and runway lighting.
The Control Philosophy Should Establish
- Flash/alternation rate
- Synchronization
- Circuit arrangement
- Control method
- Monitoring
- Fault indication
Verify the precise operating characteristic against the selected manufacturer’s documentation and applicable standard.
ICAO Requirements
When RGLs Are Required and How They Flash
Configurations A and B
- Configuration A: a pair of elevated, alternately flashing yellow lights, one on each side of the taxiway at the holding position.
- Configuration B: a row of in-pavement yellow lights across the taxiway at the holding position, alternate lights flashing together.
- ICAO Configuration B is not collocated with a stop bar. The FAA arrangement differs (combination fixtures are permitted under conditions), so follow the governing standard.
Where and How
- Configuration A is required at taxiway/runway intersections where the runway is used in RVR below 550 m and no stop bar is installed, and where RVR is 550 m to 1,200 m with heavy traffic.
- RGLs may also be provided elsewhere for added conspicuity, for example at a wide taxiway entrance.
- Flash rate is 30 to 60 per minute, with equal lit and unlit periods. FAA L-804 elevated units commonly flash at 45 to 50 per minute.
- RGLs are switched independently of stop bars.
Values are from ICAO Annex 14, Vol. I (Chapter 5, runway guard lights). Verify them against the edition and amendment in force for your project and national regulations.
Elevated RGL
Elevated Runway Guard Light
Where Used
FAA elevated RGLs (type L-804, ICAO Configuration A) per AC 150/5340-30J: at holding positions where the taxiway has no centreline lights and is 150 ft (45 m) wide or less. Where a stop bar is installed, elevated RGLs should be co-located with the stop bar regardless of taxiway width or centreline-light presence.
Assembly May Include
- Two-light RGL head
- Yellow optical assemblies and alternating light sources
- Frangible support and mounting base
- Secondary cable and isolating transformer
- Primary connector and control interface
Inset RGL
Inset / In-Pavement Runway Guard Light
Where Used
FAA AC 150/5340-30J indicates in-pavement RGLs where the taxiway has centreline lights, is wider than 150 ft (45 m), or where the applicable ILS-critical-area holding position requires it. For FAA projects the fixture specification identifies L-852G as the runway guard-light type.
Typical Installation Includes
- In-pavement RGL fixture and load-bearing housing
- Yellow optical system and alternating light sources
- Mounting hardware, sealing gasket, drainage
- Secondary cable and isolating transformer
- Primary connection

RGL Location
Location at the Holding Position
FAA In-Pavement Installations
AC 150/5340-30J places the RGL on an imaginary line parallel to and 2 ft (0.6 m) from the holding side of the runway holding-position marking, with an installation tolerance and allowance for relocation where rigid pavement joints conflict, subject to the specified conditions.
Coordinate With
- Holding-position marking
- Taxiway centreline and runway edge
- Stop bar and other visual aids
- Pavement joints, fillets, holding bays
Fixture Spacing
RGL Fixture Spacing
For FAA in-pavement RGLs the preferred arrangement spaces lights across the full taxiway width, including applicable fillets and holding bays, at approximately 3 m centre-to-centre, subject to the tolerances and provisions of the applicable guidance.
Taxiway Width + Holding Geometry + Approved Spacing + Fixture Configuration = Fixture Count
The fixture count is derived from the layout, not a fixed product quantity. Where an alternate layout is necessary, follow the current approved design and guidance.

Relationship With Stop Bar
Different Safety Functions
RGL vs Stop Bar
RGL gives an enhanced yellow warning that a runway is being approached. Stop bar gives a red stop indication at the controlled holding position. They may be adjacent or coordinated through the airport control system.
Combination Fixtures
FAA guidance permits certain combination stop-bar/RGL fixtures with dual red/yellow lenses, subject to restrictions: the yellow in-pavement lights may not be on while the stop bar operates, and dual red/yellow selection is restricted at certain ILS-critical-area holding positions.
Establish the final configuration from the approved control and lighting design.
Relationship With Taxiway Centreline
Clear, Consistent Visual Indications
Consider
- Centreline lighting beyond the holding position
- Stop-bar interlocking and RGL operation
- Holding-position marking
- Runway-entry authorization
- Low-visibility procedures
- ALCMS logic
Low-Visibility Locations
RGLs can be especially important where visibility limits increase the need for conspicuous warning. Review them together with stop bars, centreline lights, holding positions, ALCMS, surface movement control and low-visibility procedures.
The interlocking and switching philosophy is established by the approved airport operational design.

Safety
Electrical Safety — Isolation and Lock-Out
WARNING — never open a live series circuit. An open series circuit driven by a constant-current regulator can produce dangerously high voltage. Opening, cutting or disconnecting any part of an energised circuit can cause serious injury or death and damage equipment.
- De-energise the circuit at the regulator and apply the site lock-out / tag-out (LOTO) procedure before any work
- Where the circuit must be isolated or shorted, use the series circuit cut-out switch or approved isolation device — not an improvised bypass
- Verify the circuit is de-energised and the output is isolated before touching conductors, connectors, splices, transformers or fixtures
- Do not disconnect or reconnect a fixture's secondary connector while the series circuit is energised: an open secondary on a series isolating transformer can develop hazardous voltage and damage the transformer
- Work on the movement area only under the airport's permit-to-work system, with the runway or taxiway closed as required, using qualified personnel and the manufacturer's instructions
- Follow the applicable national electrical safety regulations and site procedures

FAQ
Runway Guard Light — Frequently Asked Questions
What is a runway guard light?
Runway guard lights (RGLs) provide an enhanced visual warning at runway/taxiway intersections and runway holding positions, identifying where aircraft and vehicle operators must exercise particular caution before entering or crossing a runway. An RGL supplements the holding-position environment and works with stop bars, taxiway centreline and edge lights, runway edge lights, holding-position markings and airport lighting control systems.
What colour are runway guard lights, and how do they operate?
They use alternately illuminated, unidirectional yellow lights. FAA AC 150/5340-30J describes elevated RGLs as two alternately illuminated, unidirectional yellow lights, and in-pavement RGLs as a row of alternately illuminated, unidirectional yellow lights. An RGL is not simply a steady yellow light, because the alternating illumination increases conspicuity and distinguishes it from steady-burning taxiway and runway lighting.
What are ICAO Configurations A and B?
Configuration A is a pair of elevated, alternately flashing yellow lights, one on each side of the taxiway at the holding position. Configuration B is a row of in-pavement yellow lights across the taxiway at the holding position, with alternate lights flashing together. ICAO Configuration B is not collocated with a stop bar. The FAA arrangement differs, with combination fixtures permitted under conditions, so follow the governing standard.
When are runway guard lights required, and how fast do they flash?
Under ICAO Annex 14 Vol. I, Configuration A is required at taxiway/runway intersections where the runway is used in RVR below 550 m and no stop bar is installed, and where RVR is 550 m to 1,200 m with heavy traffic. RGLs may also be provided elsewhere for added conspicuity, for example at a wide taxiway entrance. The flash rate is 30 to 60 per minute with equal lit and unlit periods, and FAA L-804 elevated units commonly flash at 45 to 50 per minute. RGLs are switched independently of stop bars. Verify these values against the edition and amendment in force for your project.
When is an elevated RGL used, and when an inset RGL?
Under FAA AC 150/5340-30J, elevated RGLs (type L-804, ICAO Configuration A) are used at holding positions where the taxiway has no centreline lights and is 150 ft (45 m) wide or less, and where a stop bar is installed they should be co-located with it regardless of taxiway width or centreline lights. In-pavement RGLs (fixture type L-852G) are indicated where the taxiway has centreline lights, is wider than 150 ft (45 m), or where the applicable ILS-critical-area holding position requires it. The final configuration is determined by the airport design and applicable standard.
Where are in-pavement RGLs located, and how far apart?
For FAA in-pavement installations, AC 150/5340-30J places the RGL on an imaginary line parallel to and 2 ft (0.6 m) from the holding side of the runway holding-position marking, with an installation tolerance and allowance for relocation where rigid pavement joints conflict. The preferred spacing runs across the full taxiway width, including applicable fillets and holding bays, at approximately 3 m centre-to-centre. The fixture count is derived from the layout, not a fixed product quantity.
How does a runway guard light differ from a stop bar?
An RGL gives an enhanced yellow warning that a runway is being approached, while a stop bar gives a red stop indication at the controlled holding position and commands the aircraft or vehicle to hold. An RGL does not replace the holding-position marking or a stop bar where one is required. They may be adjacent or coordinated through the airport control system, and FAA guidance permits certain combination stop-bar/RGL fixtures with dual red/yellow lenses subject to restrictions, including that the yellow in-pavement lights may not be on while the stop bar operates.
How are runway guard lights controlled and monitored?
Control may involve the AGL control panel and flashing controller, individual light controllers, the CCR, ALCMS, remote monitoring and incursion-prevention logic, and local maintenance controls. The control philosophy should establish the flash or alternation rate, synchronization, circuit arrangement, control method, monitoring and fault indication, so loss of the required alternation or another critical fault can be identified during inspection and monitoring. The interlocking and switching philosophy comes from the approved airport operational design.
What are the common faults with runway guard lights?
If the RGL is completely off, check for an open circuit, CCR failure, transformer failure, connector failure, cable fault, control-system fault or fixture failure. One side or section not flashing points to an individual LED failure, channel failure, wiring fault, connector problem or control or alternator failure. Steady yellow instead of alternating suggests an alternator or controller fault, incorrect wiring, a configuration error or relay failure, and a wrong flash sequence suggests a configuration, synchronization, controller or wiring problem. Low intensity can come from optical contamination, LED degradation, an incorrect CCR setting or damaged optics.
What should be confirmed before ordering runway guard lights?
Confirm the airport and project, runway/taxiway intersection and holding position, taxiway width and centreline lighting, stop-bar installation, any ILS-critical-area holding position, elevated or inset configuration, number of fixtures and spacing, the yellow unidirectional output and alternating characteristic, optical direction, intensity, series-circuit current, isolating transformer, connector type, control interface and flash controller, monitoring and ALCMS integration, housing, installation depth and drainage, applicable standard and the photometric and compliance documentation.
Which standards apply to runway guard lights?
FAA references are AC 150/5340-30J, which describes elevated and in-pavement RGLs and the configuration-selection criteria, and AC 150/5345-46F, which lists the L-852G yellow intensity and beam coverage. For ICAO, verify the applicable provisions of Annex 14 Vol. I against the project edition and amendments, and do not infer RGL layout, colour, switching or installation details from an FAA fixture designation. For India, also verify DGCA requirements, the airport-specific AGL specification, the approved holding-position layout and low-visibility procedures.
Is it safe to work on a runway guard light while the series circuit is energised?
No. An open series circuit driven by a constant-current regulator can produce dangerously high voltage, and opening, cutting or disconnecting any part of an energised circuit can cause serious injury or death. Do not disconnect or reconnect a fixture’s secondary connector while the series circuit is energised, because an open secondary on a series isolating transformer can develop hazardous voltage and damage the transformer. De-energise the circuit at the regulator, apply the site lock-out / tag-out procedure, use the series circuit cut-out switch or an approved isolation device, and work on the movement area only under the airport’s permit-to-work system, with the runway or taxiway closed as required. See the electrical safety warning on this page.
