Buyer's checklist
What to check before buying a used tail light
- Look for cracks in the lens — even hairline cracks let in moisture and will eventually fog the housing.
- Confirm the assembly matches your trim level. Base and higher trims often use different tail light designs.
- Check that the wiring harness connector and all bulb sockets are intact.
- Verify inner vs outer — many vehicles use separate inner (trunk lid) and outer (quarter panel) tail lights.
