Modern factory headlights do more than light the road. They switch high beam on and off by themselves, steer into corners, level when the truck is loaded, and on some vehicles carve a dark spot out of the high beam around oncoming cars. Every one of those functions lives somewhere specific: some in the vehicle, some in the lamp. When you replace the lamp, what lives in the vehicle keeps working, and what lived in the lamp carries over when the new lamp has that hardware too. Knowing which is which is the whole answer to "will my [feature] still work."
The quick answer. On most vehicles, your factory lighting features keep working after a RIGNOX headlight swap. Only a small number of high-trim vehicles with factory matrix / adaptive (ADB) or swiveling (AFS) headlights are the exception, and those trims aren't listed as compatible on the product page.
If the feature is a signal the vehicle sends to the headlight, it carries over. If the feature is a motor, a sensor, or a per-segment controller inside the headlight, it carries over only if the new lamp has that hardware too.
The feature-by-feature answer
| Factory feature | Where it lives | After a RIGNOX headlight |
|---|---|---|
| Automatic headlights (on at dusk) | Vehicle: light sensor and BCM | Works. The vehicle turns the low-beam circuit on; the lamp doesn't know or care why. |
| Auto High Beam (AHB / Auto Beam / IntelliBeam / HBA) | Vehicle: windshield camera, decides high on/off | Works. The camera switches the high-beam circuit; our high-beam group responds to it like any other high-beam command. |
| Daytime running lights | Vehicle sends the DRL signal; lamp provides the DRL | Works, with our DRL. The factory DRL logic (on with engine, dims or off with headlights) drives our light bar instead of the factory one. |
| Turn signals, hazards | Vehicle circuit | Works, in amber — sequential on most builds, a standard flash on a few; the product page says which. See hyperflash if the rate changes. |
| Fog lights, cornering lights in the bumper | Separate lamps | Unaffected. Not part of the headlight. |
| Headlight washers | Nozzles in the bumper, pump in the vehicle | Usually unaffected. On the few vehicles where the washer jet mounts to the lamp, the product page's Compatibility section says so. |
| Headlight leveling: the dash dial, or automatic self-leveling with load | The vehicle sends the command (dial or ride-height sensors); a motor inside the lamp moves the beam | Kept. You never lose the ability to level the beam; what changes is how you do it. Some models ship with a leveling motor in each housing; the product page's spec table says "Powered leveling" in the Aim Adjustment row, and on those the dash dial and the vehicle's auto-leveling keep working exactly as before. The rest are leveled with adjustment screws on the housing: set the aim at install, and re-set it with the screws if the load or ride height changes for good; the dash dial, if the vehicle has one, no longer moves the beam. A leveling motor only does something on a vehicle that had leveling to begin with; on a vehicle that never had a dial or auto-leveling, the powered models are aimed with their screws like the rest. |
| Adaptive / swiveling headlights (AFS, cornering low beam) | Swivel motor inside the factory lamp | Not compatible. No RIGNOX housing has a swivel motor, and on most AFS vehicles the lamp connector and control module differ from the halogen trim's. We do not list our headlights as fitting factory-AFS trims. |
| Adaptive Driving Beam / matrix / "glare-free" high beam (ADB, AHS with segments, Matrix LED, Pixel) | Per-segment drivers inside the factory lamp, controlled by the vehicle's camera and computer | Not compatible. We don't list our headlights for factory ADB / matrix trims. |

Why AHB survives and ADB doesn't
They sound similar and are often sold under the same "adaptive" label, so this is the distinction that causes the most confusion.
Auto High Beam is a decision, not a beam. The camera watches for headlights and tail lights ahead; when it sees them it switches the whole high beam off, and when the road is clear it switches the whole high beam back on. The headlight's only job is to be on or off. Any headlight can do that, so the function carries over intact.
Adaptive Driving Beam is a beam, not just a decision. Instead of switching the high beam off, the vehicle keeps it on and dims only the segments pointing at the other car. That requires a headlight with many independently driven segments and a data connection to the vehicle's controller that tells each one what to do. Aftermarket headlights have neither: the projectors are grouped, and the lamp has no data link, only power lines for low, high, DRL and turn. That's why factory ADB / matrix trims aren't listed as compatible. Our projector-count guide explains why a multi-projector aftermarket lamp doesn't restore ADB, even if it looks like one that could.
How to find out what your factory headlight has
Owners frequently don't know whether their truck came with adaptive lighting, because the higher-trim features aren't labeled on the lamp. Three quick checks:
- The window sticker or build sheet. Look for "Adaptive Front Lighting," "Adaptive Headlights," "Matrix," or "Adaptive High Beam." Plain "Auto High Beam" or "High Beam Assist" is the simple version and is fine. For Auto-Leveling, check the product page: models with Powered leveling keep it, and where a model doesn't support factory auto-leveling, its Fits line says so.
- Turn the wheel with the low beams on, engine running, parked facing a wall. If the beam swings with the wheel, you have AFS.
- Watch the beam on a wall while a passenger gets in and out. On an auto-leveling vehicle you can sometimes see the beam settle on the wall as the load changes. A dash leveling dial means manual leveling. Either way you keep leveling: with a RIGNOX headlight whose spec table says Powered leveling, the dial and auto-leveling keep working; on the others you level with the adjustment screws instead.
If either of the first two shows adaptive behavior: factory ADB / matrix and AFS trims aren't listed as compatible.
The carry-over rule. Auto headlights, auto high beam, DRL logic and turn signals are vehicle-side and carry over. Swivel motors and matrix segments are lamp-side and do not. You can always level the beam: our powered-leveling models keep the dial and auto-leveling, and the rest are leveled with adjustment screws. Factory matrix / ADB and AFS trims aren't listed as compatible.
The short version
- A feature carries over if the vehicle only needs to send the lamp a signal. It is lost if it needed hardware inside the lamp that the new lamp doesn't have.
- Auto headlights, Auto High Beam, DRL behavior, turn signals: work.
- Leveling: you can always level the beam. Models whose spec table says Powered leveling keep the dash dial and auto-leveling working; the rest are leveled with adjustment screws. A leveling motor only matters on a vehicle that had leveling to begin with.
- Swiveling AFS: not present; AFS trims are not listed as compatible.
- ADB / matrix high beam: not compatible; those trims aren't listed.
- Check your build sheet and turn the wheel against a wall to find out what you have.
See what is available for your vehicle in RIGNOX LED headlights by vehicle. On each product page, the Fits line gives the years and factory headlight type the assembly is built for; "all trims" means every trim built with that factory headlight. Factory ADB / matrix and AFS trims aren't listed as compatible.
