We have H4 / H7 / H11 / H13 LED headlights. H4 and H13 headlights are Hi/Lo beam lights while H7 and H13 are not dual beam lights. So the type of Cree chip in H4 and H13 is XHP50 and the type of Cree chip in H7 and H11 is XML2.
Using high beam light you can see the distance clearly, it illuminate large area in the distance. Low beam light focus on the near area in the front of the car and gives you much more clear visibility of that area.
Our car headlight makes you driving safety in the darkness and at night. They illuminate the front clearly so you can see the cars or other object before you vehicle.
