High-quality reflectors ensure night safety.

Aftermarket headlight reflectors often lack reflectivity.

ADCARLIGHTS' high-end mold core electroforming technology ensures over 98% reflectivity, enhancing vehicle recognition and promoting safe driving.

What does light pattern mean and why is it important? ADCARLIGHTS ensures superior road visibility with its advanced light pattern and trapezoidal design.

Achieve optimal light distribution and wider angle illumination for poorly lit areas.
