On a big rig, a low beam out is often a bulb, a wire or a burned connector, not the headlight. A "Low beam bulb fault" message can point either way. If the fault is in the wiring, the plug or an aftermarket LED set, have a truck shop near you sort it out before anything ships. If it is the factory headlight itself, send photos. Not sure? Read [Can My Headlight Be Repaired?](https://headlightrepairshopusa.com/guides/can-my-headlight-be-repaired/) ## What we fix inside a factory truck headlight - An LED beam that flickers, dims or stays dark - A DRL strip or running light going dim or out - Water that stays inside after a wash - A cracked or hazy outer lens Tell us the symptom and we'll confirm whether the LED or DRL module can be repaired. If a turn signal flashes white, send photos and we'll confirm in your quote whether that section can be repaired. A hazy lens gets a new one: polishing strips the factory coating and the haze tends to come back. Tell us what happened to the lens and we will confirm whether the outer lens can be replaced on your headlight.

Droplets that stay inside a Western Star headlight, on a 5700XE or another model, mean a seal has failed.

No, only factory headlights. For an aftermarket LED set, a conversion kit or a resistor problem, go back to the shop that installed it or a local truck shop. ### Who pulls the headlight off the truck? You or your shop. Only the headlight ships, and it comes back ready to go back on and aim. ### What should I send with the quote request? The make, model and year of the truck, photos of the headlight lit and of the fault, and the part number on the housing label. ## Learn more - Why we don't polish truck lenses: [Headlight Repair vs. Headlight Restoration: What Is the Difference](https://headlightrepairshopusa.com/guides/headlight-repair-vs-restoration/). - [Headlight Repair Services](https://headlightrepairshopusa.com/headlight-repair/) ## Send photos of your rig's headlight Tell us the make, model and year, add photos and the part number, and your written quote comes before you ship.
