Improve airport lights in MSFS 2020 with sharper settings, better scenery, and practical fixes for lights that are dim, blurry, or missing.
To improve airport lights in MSFS 2020, increase render resolution and Objects Level of Detail, use stable anti-aliasing, enable Bloom only if its halos look natural, and raise shadows, ambient occlusion and reflections. If an airport remains poorly lit, install a good scenery replacement or troubleshoot conflicting airport packages.
MSFS 2020 has no single airport-light quality or intensity slider. Graphics settings control clarity, glow, shadows and reflected light, while each airport's scenery controls the number, position and type of lights.
Which graphics settings improve airport lights in MSFS 2020?
Start with Render Scaling, anti-aliasing and Objects Level of Detail. These have the clearest effect on distant runway lights, taxiway lights and custom light fixtures.
| Setting | What it changes | Practical choice |
|---|---|---|
| Render Scaling | Definition of small and distant lights | Use native resolution or close to it. Low scaling makes lights merge, shimmer or disappear. |
| Anti-Aliasing | Stability while moving the camera | TAA is a dependable baseline. Quality upscaling can recover performance, but aggressive performance modes may soften or ghost lights. |
| Objects Level of Detail | Distance at which custom fixtures and airport objects remain visible | Raise it gradually while watching frame rate. Terrain Level of Detail has less direct effect on airport lamps. |
| Bloom | Glow around bright points | Enable it for visible halos, but disable it if runway lights become oversized blobs. Bloom does not add missing illumination. |
| Contact Shadows and Ambient Occlusion | Depth around terminals, stands and light fixtures | Medium or high settings help ramp lighting look grounded. |
| Reflections | Light reflected by wet aprons and terminal surfaces | Increase it if the GPU has spare capacity; it does not strengthen the actual runway lights. |
| Shadow Maps and Terrain Shadows | Shadows cast around airport buildings and floodlit areas | Raise these after resolution and object detail, as their performance cost can be substantial. |
Light Shafts mainly affect visible rays through mist or cloud rather than runway-light intensity. Our setting-by-setting MSFS graphics guidance explains which visual options deserve priority when performance is limited.
Why are airport lights missing or too dim?
If only one airport is dark, its scenery is the likely cause; if every airport is dark, check graphics, display and add-on settings. Use this sequence to isolate the fault:
- Create a controlled test. Load a large airport after nightfall with clear weather. Haze, fog and low cloud can turn individual lights into diffuse glow, making diagnosis harder.
- Compare cockpit and external views. Bright instrument panels and cockpit floodlights reduce outside contrast. Turn them down; if the airport looks normal externally, the scenery itself is probably working.
- Check installed content. Open Content Manager and confirm that the relevant handcrafted airport, world package or purchased scenery is installed and updated.
- Remove duplicate airport packages. On PC, temporarily empty or rename the Community folder and test again. On Xbox, disable or remove optional airport content through Content Manager. Two packages editing the same airport can suppress lights, duplicate objects or load an older layout.
- Confirm the airport should be lit. Small airfields may have sparse or no night lighting. PAPI and VASI units are directional, while approach-light systems may be fitted to only one runway direction.
- Test without global lighting modifications. A mod that changes colours or emissive effects across the simulator may conflict with custom airport lighting.

Do airport scenery add-ons improve lighting?
Yes, a well-made airport add-on can improve light placement, apron floodlighting, illuminated signs, terminal windows and reflections. This is usually the only effective fix when the default airport has missing fixtures or an inaccurate layout.
Run only one replacement for each airport unless its documentation explicitly supports another package. When choosing an upgrade, look for custom runway and taxiway lights, stand lighting, emissive textures and a clear compatibility statement. Our selection of freeware airports with upgraded airfield detail is a useful starting point.
Global visual modifications are broader: they may alter light colour, bloom or night brightness at every airport, but they cannot correct wrongly positioned fixtures. Check our overview of graphics and lighting add-ons suitable for Microsoft Flight Simulator before combining one with custom scenery.
Why do runway lights flicker or look blurry?
Blur, shimmer and light trails usually come from low internal resolution, temporal upscaling or excessive Bloom rather than the airport model. The visible symptom points to the most useful adjustment:
- Sparkling distant lights: raise Render Scaling and use TAA or a quality-focused upscaling mode.
- Large fuzzy halos: disable Bloom temporarily and check the monitor's HDR, brightness and black-level calibration.
- Trails while panning: turn off Motion Blur and compare TAA with the selected temporal upscaler.
- Flickering at one airport only: remove duplicate scenery and test the airport without Community add-ons.
- Flickering at every airport: reset graphics options to a known preset, then change one setting at a time. Also compare the available DirectX modes after restarting the simulator.
