Helideck Status Lights
Helideck status lighting signals to an approaching pilot whether a deck is available, with a flashing red state indicating the deck is unsafe to land, controlled from the deck operator's station under CAP 437. NLS sources and installs helideck status lighting for helideck and heliport projects in Saudi Arabia.
Inside the Helideck Status Lights
Helideck status lights tell an approaching pilot in one glance whether the deck is available to land. The assembly pairs a two-colour or dedicated red lens with an LED source and a control interface wired back to the deck operator's station, so the displayed state always matches the operator's own decision.
01
Light Housing
The sealed enclosure holds the lens, LED source and wiring against the deck's marine or rooftop exposure, keeping the fixture operational through salt spray, washdown and vibration.
02
Status Lens Assembly
Displays the deck status as a distinct colour, typically red for unsafe and green or off for available, shaped and filtered so the state is unambiguous from the approach path.
03
LED Source Module
Generates the light output behind the status lens at the intensity needed for the status to remain legible in daylight and at night from the pilot's viewing angle.
04
Status Control Interface
Receives the go or no-go command from the deck operator's station and switches the displayed colour accordingly, forming the direct link between the operator's decision and what the pilot sees.
05
Mounting Bracket
Fixes the fixture at the deck perimeter position and orientation the layout requires, low profile enough to stay clear of the rotor disc and passenger movement.

Helideck status lights are the switchable coloured perimeter units that communicate the deck's operational status to an approaching pilot before touchdown, distinct from the fixed TLOF perimeter lighting that simply marks the deck boundary at all times. A flashing red status light signals the deck is unsafe to land under CAP 437, the UK helideck design guidance widely referenced for offshore and onshore helideck lighting worldwide, alongside ICAO Annex 14 Volume II for the general heliport lighting framework. Additional status states, such as a clear or restricted indication, are configured by the deck operator's own procedures rather than fixed by CAP 437 itself.
Status lights are switched from the helideck operator's control station, whether that's a dedicated helideck control room on an offshore platform or a simpler local control point on a hospital rooftop pad or industrial site helideck, and the switching logic ties into the deck's operational procedures: a deck goes red the moment an obstruction, weather limit, or safety condition takes it out of service, and green only when the deck operator has confirmed it clear. This makes the control panel and its integration into deck operating procedure as much a part of the specification as the light fixtures themselves.
NLS sources status light fixtures to IEC 60598 luminaire safety, in the perimeter-mounted format CAP 437 specifies, matched to a control panel sized for the number of status states a specific deck's operating procedure requires, whether a simple red/green two-state system or a more elaborate scheme with an amber intermediate state. This sits inside the same coordinated helideck lighting design as TLOF perimeter lighting, floodlighting, and identification beacons rather than as an isolated add-on fixture.
Offshore and elevated onshore helidecks in the Gulf region see combined wind, salt-air, and high-heat exposure that pushes fixture and control panel housing selection past a standard onshore rating. IP66 or higher sealed enclosures, corrosion-resistant materials on the fixture body and control panel housing, and wind-rated mounting brackets matter more on an elevated or offshore deck than on a sheltered ground installation, and NLS checks these against the specific site's exposure category before recommending a fixture and control package.
NLS delivers helideck status lighting as part of a turnkey helideck package, design, supply, installation, and commissioning under one desk, sourced from established international aviation lighting manufacturers, priced in USD for supply and SAR for the customer-facing offer. A project team typically shares the deck's operating procedure and status states required, and NLS returns a fixture, control panel, and switching logic recommendation with a matched quote.

Frequently Asked Questions
What's the difference between helideck status lights and TLOF perimeter lights?+
TLOF perimeter lights are fixed green and simply mark the deck boundary at all times. Status lights are switchable, with a flashing red state under CAP 437 indicating the deck is unsafe to land, controlled from the deck operator's station.
What standard governs helideck status light colours?+
CAP 437 specifies a flashing red state indicating the deck is unsafe to land; additional status states are configured by the deck operator's own procedures, within the wider ICAO Annex 14 Volume II heliport lighting framework NLS engineers to.
Who supplies helideck status lighting in Saudi Arabia?+
NLS sources helideck status lighting and control panels engineered to CAP 437 and ICAO Annex 14 Volume II and delivers them turnkey, design, supply, installation, and commissioning, for helideck and heliport projects across the Kingdom.
