They are Xenon lights NO they are NOT Hi-Lo. So be aware. I didnt know until I got them but for $25 bucks what else can you as for? I installed them in less than 10 minutes took the car out to check them out came back in the garage readjusted them in less than 5 and I was good to go. I loved them even tho I dont have Hi beams. Because they are very nice and really bright that I see the road perfectly and it also lights up all road signs pretty well. I guess they come pre angled to do so. I love them. Never even thought about returning them they are just perfect for me.
