Therey okay but the built in LEDs are not as bright as I would want. Condensation builds up in the housing so I had to put 2 small holes in the lights and they dont come with directions to wire them in. But overall it was an improvement just not a 300$ improvement and I paid 500$ for the hids they say they had but didnt. There all halogenMisleading titleThis is just a halogen kit but not for your HID bulbs. Keywords were used incorrectly here and were very confusingI had to return it because I thought it was for HID since it was labeled HID type kit. Unfortunately, there was a halogen bulb that was hardwired into the connectors. Thus, I was unable to transfer my stock HID over. Agian, this is a halogen kit but not a HID type kit as advertised. Amazon please make correction to the title.Ordered black but got crome fit well no instructions to wire halo lightslights look cheapFirst of all, the wiring on this unit does not match the wiring of the car, so it's not plug-and-play. It also comes with no wiring instructions. But that doesn't even matter because it doesn't actually work with your HID system (despite what it says).Even though they make an "HID Type" and a "Halogen Type," you can NOT use your factory HID with this.You basically put your factory HID system aside and replace it with the halogen system these come with. I confirmed this with Spyder Auto.I have NO IDEA why the hell they didn't make a version that uses factory HID.Instead, it appears the only option is to purchase a separate aftermarket HID kit that fits in this thing, which is damned retarded considering we already have extremely high end HID in our cars...I had the same problem after purchasing this.Even though they make an "HID Type" and a "Halogen Type," you can NOT use your factory HID with this.You basically put your factory HID system aside and replace it with the halogen system these come with.
