How to find the right Automotive Headlight Housings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Automotive Headlight Housings
- Certification
- Prefer CAPA-certified or DOT/SAE-marked replacement housings. CAPA certification checks that an aftermarket part matches OE fit and performance.
- Headlamp type match
- Match halogen versus HID versus LED, and reflector versus projector, to the car's wiring and bulbs. Swapping lamp types without the matching wiring or leveling causes errors and glare.
- Sealing and venting
- Check the seal bead and vent caps on arrival. Poor sealing on cheap housings causes condensation.
- Replace in pairs
- Replace both sides if the other side is noticeably yellowed or different in color. Mismatched headlights look odd and may light unevenly.
Brands that matter
- TYC: Widely used aftermarket housings, many CAPA-certified.
- Depo: Aftermarket housings with broad coverage, including CAPA-certified options.
- Hella: OE-level units for many European vehicles.
What to avoid
- Unbranded 'custom' projector housings with no DOT/SAE marking.
- Housings bought for the wrong lamp type on cars with automatic leveling.
