Crane & Construction Site Obstruction Lights Solution
Crane Obstruction Lights are a mandatory safety requirement for tower cranes, luffing cranes, and other tall construction equipment near airports, urban flight corridors, and low-altitude helicopter routes. But cranes present a lighting challenge that permanent structures — towers, buildings, chimneys — simply don’t have: the structure moves, rotates, and changes height throughout the project.
A tower crane’s jib slews continuously to reposition loads; angular booms tilt up and down; climbing cranes grow taller floor by floor as a skyscraper rises, meaning the lighting configuration that was compliant last month may no longer be adequate today. Add to this the reality of a construction site — temporary power, tight project timelines, frequent equipment relocation between sites, and contractors who need compliance in place before permanent electrical infrastructure exists — and it becomes clear why crane obstruction lighting requires a fundamentally different product approach than lighting a fixed telecom tower or building rooftop.
YFFY Lights supplies complete crane and construction site obstruction lighting systems — solar-powered, wireless, pivot-mounted, and designed for fast relocation — helping crane rental fleets, general contractors, and EPC teams maintain continuous aviation compliance through every phase of a project, without waiting on permanent power or specialized installation crews.
Which Crane Obstruction Light Do You Need?
| Crane / Site Condition | Required Light Type (ICAO/FAA) | Placement | Notes |
| Crane height ≤ 45m (150ft) AGL | Low Intensity, red steady or flashing (L-810) | Two or more lights at highest point | Ensures visibility from any approach angle |
| Crane 45m – 105m AGL | Low Intensity at cathead + jib/counter-jib ends | Typically 3 lights: cathead, jib tip, counter-jib tip | Common configuration for standard tower cranes |
| Crane exceeding 105m AGL, or crane exceeds surrounding structures by 45m+ | Medium Intensity red flashing (L-864) at top, low-intensity at intermediate levels | Top + intermediate tiers | Applies even if the crane itself is short, when it exceeds nearby building/terrain height by 45m+ |
| Crane with angular/luffing boom | Pivot-mounted lights on rotation axis | Mounted so lights stay level and unobstructed as boom tilts | Standard point-mount fixtures risk being blocked by crane structure at certain boom angles |
| Aviation-painted crane (red/yellow/orange) | Red obstruction lights | Standard configuration | Painting reduces day-marking lighting requirements in some jurisdictions |
| Unpainted crane | Red/white medium-intensity dual lighting | Day (white) / Night (red), auto-switching | Provides day and night visibility without requiring structure repainting |
| Climbing/self-raising tower crane | Reassessed at each height increase | Lighting configuration re-evaluated as crane climbs | Compliance must be maintained continuously through the entire build sequence |
Note: Requirements vary by country and by proximity to airports — always confirm thresholds with your local civil aviation authority. YFFY Lights’ engineering team provides a free pre-project compliance review based on your specific crane model and site.
Crane & Construction Site Obstruction Lights System Solution
Low Intensity Obstruction Lights (Type A/B) cover standard tower cranes up to 105 meters, typically mounted at the cathead, jib tip, and counter-jib tip to ensure the crane’s full working outline is visible from any direction — the most common configuration for construction-site cranes.
For taller cranes, or cranes that exceed surrounding structures by more than 45 meters, Medium Intensity Obstruction Lights (L-864) provide higher-visibility red flashing at the crane’s highest point, combined with low-intensity lights at intermediate levels for full-height marking.
Standard fixed-mount lights can be obstructed by a crane’s own structure when the boom tilts. YFFY’s pivot-mounted obstruction lights stay level and unobstructed regardless of boom angle or jib rotation, ensuring continuous pilot visibility even during active lifting operations.
Construction sites frequently lack permanent electrical infrastructure, especially in early project phases. Solar-powered obstruction lights install in minutes with no wiring runs up the mast — using high-efficiency solar panels and battery backup rated for 15–20 days of autonomous operation, ideal for cranes on sites with temporary or generator-only power.
For cranes without aviation-standard paint markings, medium-intensity dual lighting automatically switches between white flashing (day) and red flashing (night) based on ambient light — providing full day/night compliance without requiring the crane to be repainted.
Crane rental companies and multi-site contractors need lighting that moves easily between projects. YFFY’s quick-mount, self-contained obstruction lights require no site-specific wiring or custom bracketry, making them practical for fleets that redeploy the same crane units across multiple job sites throughout the year.

Crane & Construction Site Lighting Compliance Standards
ICAO Annex 14
ICAO Annex 14 — Aerodromes, Chapter 6, provides the global baseline for temporary and mobile obstacle lighting, including cranes, applying the same low/medium/high intensity classification framework used for permanent structures.
FAA AC 70/7460-1L
In the United States, the FAA Advisory Circular 70/7460-1L sets specific tower crane lighting requirements based on height above ground level (AGL) — including guidance for cranes up to 150ft, 150–350ft, and beyond — and requires each crane to be individually evaluated for its specific lighting configuration.
A frequently overlooked requirement: a crane that is itself relatively short can still require obstruction lighting if it exceeds the height of surrounding buildings or terrain by 45 meters or more. This means lighting requirements should be assessed relative to the construction site’s context, not just the crane’s absolute height — a common compliance gap on urban infill projects.
For climbing and self-raising tower cranes, lighting requirements must be re-evaluated every time the crane’s height increases. A configuration that was compliant at 80 meters may require additional intermediate-level lights once the crane reaches 130 meters — an ongoing responsibility for site safety teams throughout the build.

Frequently Asked Questions
Most jurisdictions require obstruction lighting for cranes exceeding 45 meters (150 feet) AGL, following ICAO/FAA guidance. However, a shorter crane can still require lighting if it exceeds surrounding buildings or terrain by 45 meters or more — always assess height relative to the site context, not just the crane’s absolute height.
Yes. Self-raising and climbing tower cranes change height throughout the project, and lighting requirements should be reassessed at each significant height increase. A configuration compliant at an early project phase may need additional intermediate lights as the crane climbs higher.
Standard fixed-mount lights can become obstructed by the crane’s own structure at certain boom angles. Pivot-mounted obstruction lights are designed to remain level and unobstructed regardless of jib rotation or boom tilt, maintaining continuous pilot visibility during active operations.
Yes. Solar-powered obstruction lights are the standard choice for construction sites, since they install without wiring runs and don’t depend on the site’s often-temporary or generator-based power supply — a practical necessity in early project phases.
In some jurisdictions, cranes painted in aviation-standard colors (red, yellow, or alternating red/yellow) may have reduced daytime lighting requirements compared to unpainted cranes, which typically need red/white dual-mode lighting for full day/night visibility. Confirm specific requirements with your local civil aviation authority.
Yes. YFFY’s self-contained, quick-mount obstruction lights are designed for crane rental fleets and multi-site contractors who need to redeploy the same units across different projects without site-specific wiring or custom installation each time.
