Buyer's checklist
What to check before buying a used headlight assembly
- Check for lens clarity — cloudy, yellowed, or hazed lenses reduce light output and can fail inspection.
- Look for moisture damage or watermarks inside the housing. A dried-out water line means a broken seal.
- Confirm whether the unit is halogen, HID/xenon, or LED — the wrong type won't plug in correctly and may need different ballasts.
- Inspect the tabs and mounting points for cracks. Headlight tabs are fragile and a broken tab means the assembly won't seat properly.
