If the wiring checks out, the headlight itself is the next suspect. Tell us the symptom and we'll confirm whether the LED or DRL module can be repaired. Sealed LED units and how they are opened and resealed: [LED Headlight Repair](https://headlightrepairshopusa.com/headlight-repair/led-headlights/). ## Wiring, bulb or the factory headlight On a truck, a missing low beam often comes down to a wire, a corroded plug or aftermarket LED bulbs. Those are fixed on the rig by a local truck shop, and we don't repair aftermarket sets. When the wiring checks out and the factory headlight still won't light, it's worth a quote. The checks, in order: [Headlight Not Working? Bulb, Wiring or the Headlight Itself](https://headlightrepairshopusa.com/guides/headlight-not-working/). ## Kenworth W900 headlight: what we look at On a long-nose W900, send photos of the factory headlight lit and of any crack or fog behind the lens. Your quote confirms whether the beam, the seal or the lens can be repaired. A cracked or hazy outer lens gets a new one, never polishing, since that strips the factory coating. Tell us what happened to the lens and we will confirm whether the outer lens can be replaced on your headlight. Other Kenworth models can be sent too, with photos and the part number on the housing. ## Moisture inside a Kenworth headlight Fog that clears once the lights warm up can be normal. Droplets that stay after a wash or a rainy run mean a seal has failed, and water can reach the LEDs. The repair opens the headlight, dries it and seals it again, as in [Headlight Condensation Repair & Resealing](https://headlightrepairshopusa.com/headlight-repair/condensation/). ![Droplets of moisture inside the headlight of a long-nose truck parked in the rain](https://headlightrepairshopusa.com/img/trucks/kenworth-w900-headlight-moisture-droplets.webp) ## Pricing for owner-operators and fleets Repairing the factory headlight keeps its fit and its connectors.
