The fitment system says the bulb fits my car, why the lights are not fit actually?

The same vehicle model may have more than 2 h-e-adlight configurations, our light may only fit one of them. Read the Note carefully to check which assembly fits this light before you buy. Or you can directly contact our support team for help.

What I have is aftermarket h-e-adl-ight assembly, can I follow the Fitment system to select lights?

No. Our Fitment system can only make sure the matching the original assembly. Aftermarket assembly may be different with the original one.

Why the bulbs doesn’t work suddenly after a short period of using?

(Method: Check the applicable HID bulb models on the original car ballast). Incompatible ballast may cause the bulbs out. If your bulbs doesn’t work within 3 months, check whether the ballast’s type is fitted
