Obstruction Light Monitoring
Obstruction light monitoring is a remote surveillance service that tracks lamp status, power supply and flash synchronization across a structure's obstruction lighting system, alerting the operator the moment a fault occurs instead of waiting for the next physical inspection. NLS deploys and manages monitoring systems alongside its obstruction lighting supply across Saudi Arabia so structures stay continuously compliant.
Inside the Obstruction Light Monitoring
An obstruction light monitoring system pairs sensing modules at each beacon with a communications link and a central software platform, so lamp status, power supply and flash synchronisation across a whole structure are visible from a single dashboard. Together these parts turn a fault that would otherwise wait for the next site visit into an immediate alert.
01
Beacon Sensor Module
Attaches to each obstruction light and reads lamp current, flash timing and photocell state directly at the fixture, catching a failing lamp or driver before it goes dark.
02
Communications Gateway
Collects readings from every sensor module on the structure and relays them to the monitoring platform over a cellular, radio or wired link, giving the system reach on structures where beacons are spread across a wide area.
03
Monitoring Software Platform
Displays live status for every monitored beacon, logs fault history and issues alerts to the operator the moment a lamp, power supply or synchronisation fault is detected.
04
Power Supply Monitor
Tracks voltage and current at the fixture's power feed, distinguishing a lamp failure from an upstream power fault so maintenance crews are dispatched with the right diagnosis, not a guess.
05
Alert Notification Unit
Pushes fault alerts to the operator by the notification channel configured for the site, keeping the structure's obstruction lighting compliance visible without requiring a physical inspection round.

Why a failed obstruction light is a compliance problem, not just a maintenance one
A tower, crane or stack fitted with obstruction lights is compliant only while those lights actually work. A single failed lamp on an otherwise correctly lit structure creates a gap that is invisible from the ground during the day and often unnoticed until a scheduled inspection, an aviation authority query, or worse, an incident. Obstruction light monitoring closes that gap by watching the system continuously rather than periodically.
What the service tracks
A monitoring deployment typically reports lamp on and off status, power supply continuity (grid, generator or solar battery state), and, on structures with multiple synchronized high intensity fixtures, whether the flash pattern remains coordinated across units. Alerts are pushed to the responsible party by SMS, email or a monitoring dashboard depending on the system and the client's preference, so a fault triggers action within hours rather than being discovered weeks later.
Method
NLS assesses the structure's existing lighting system, or specifies monitoring as part of a new obstruction lighting supply, and fits sensors and a telemetry unit that communicate over cellular or satellite connectivity depending on site location. For remote or offshore structures with no reliable cellular coverage, satellite-based telemetry keeps the monitoring link active regardless of terrain. The system is commissioned alongside the lighting itself, with test alerts verified before handover so the client knows the alerting chain actually works before it is needed.
Deliverables
Clients receive a working monitoring link tied to their obstruction lighting, an agreed alert routing (who is notified and how), and, where requested, a periodic status report summarizing uptime and any fault events over the reporting period. This turns obstruction lighting from a fit-and-forget installation into a continuously verified compliance asset.
Who this suits
Monitoring is most valuable on structures where a fault would take time to notice through routine site presence, remote towers, offshore platforms, tall structures with multiple high intensity fixtures, and any site where the operator cannot practically walk past the structure and look up every night. NLS offers monitoring as an add-on to any new obstruction lighting supply and as a standalone retrofit onto existing lighting systems that currently have no visibility into fault status.

Frequently Asked Questions
How quickly does obstruction light monitoring detect a lamp failure?+
Monitoring systems check lamp and power status continuously and push an alert as soon as a fault condition is detected, typically within minutes, rather than waiting for the next scheduled site visit or inspection.
Can monitoring be added to an obstruction lighting system NLS did not originally install?+
Yes. NLS assesses existing obstruction lighting systems and fits monitoring sensors and telemetry as a retrofit, independent of who originally supplied the lights.
Does obstruction light monitoring work on offshore or remote sites without cellular coverage?+
Yes. For sites without reliable cellular coverage, NLS specifies satellite-based telemetry so the monitoring link remains active regardless of terrain or distance from populated areas.
