The step people skip is aiming. A new headlight installed without checking the aim can blind oncoming drivers or leave a dark spot right where you need to see. Most truck shops can check and adjust aim quickly with the right equipment, and it's worth doing any time a headlight housing is replaced, not just when it feels obviously off. Check that any integrated turn signal or marker light wiring is reconnected correctly, since commercial truck headlight assemblies often combine multiple functions in one housing.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWill a Freightliner headlight from one body style fit another year?\u003c\/h3\u003e\n\u003cp\u003eNot reliably. Body style changes within the same model line are common on commercial trucks, and headlights from one generation generally don't fit a different one. Match the OE part number or compare the housing shape before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I replace just one side instead of the pair?\u003c\/h3\u003e\n\u003cp\u003eYes, if only one side is damaged and a single-side listing is available for your truck. Just confirm which side — driver or passenger — matches what you need.\u003c\/p\u003e\n\u003ch3\u003eCan I upgrade from halogen to LED?\u003c\/h3\u003e\n\u003cp\u003eSometimes, but check connector and wiring compatibility first. Some LED assemblies are direct swaps; others need an adapter or additional wiring work.\u003c\/p\u003e\n\u003ch3\u003eDo commercial truck headlights need to be aimed after installation?\u003c\/h3\u003e\n\u003cp\u003eYes. A misaimed headlight is a safety issue for you and oncoming traffic, and it can also fail a roadside inspection even if the light itself works fine.\u003c\/p\u003e\n\u003ch3\u003eDo you ship truck headlights worldwide?\u003c\/h3\u003e\n\u003cp\u003eYes, we ship worldwide.
