I love these bulbs. There has been an issue with the color of one being cooler than the other, but the company sent me a replacement. Even then one side seems warmer than the other. However, the brightness of these bulbs are no joke. You definitely need to adjust them right away. I have a place in town that I go and park to get that perfect adjustment. It was a little difficult to find mounting spaces for the ballast, but the thin sized ballast made it easier for the install. I also bought the gen 3 h11 leds for my fog lights and they look amazing. The entire package looks tasty!!! However, I was unable to get any of the gen 3 or S-V.4 h7 bulbs in my car due to the off center mount. I finally had to go with putco to get an led bright. I recommend these hid for cars that want to get rid of the gimmick look and go all in. I was a gimmick bulb user for years and now I will never go back. I'll include pictures of my installation so you can see.

Best quality hid kit

My Chevrolet suburban came with halogen lights and I decided to change to H ID. Night and day difference. I'm glad I bought these and I know it will keep me safe at night because I will be able to see better.

Very simply, these lights are nice and bright. I chose the pure white option, and darn if they are not very very close to the LED running lights, and fog lights. No issues with faulty parts, and everything connected to itself just fine. I dont know how the lights draw enough power from the standard connections to run the lights, but they do. They fire immediately, and do take about 10 or so seconds to reach full power. You will get people thinking you have high beams on, until you turn on the high beams.
I put these in a 17 chrysler 300. Chrysler is notorious with their CanBus systems, but I have not had one error on my dash. They turn on at night and turn off during the day. No muss, no fuss.
Now on to the cons
The directions and tolerances are a bit off. You have to drill a hole in the dust cap, and the size might be nessicary for the rubber stopper, but not big enough for the hardware. I had to do some modifications to get everything to fit, but eventually it did fit. All the hardware is tight and waterproof. No infiltration inside the lenses, and even engine compartment cleaning has had no impact. The wiring is a touch short which causes issues in placement of the hardware. You would think that such a large engine bay would provide much room, but it really doesn't.
I have had them in for about 4 months now and not one issue.
I will give two thumbs up

I can't believe how bright the are!

I Have Installed this bulb in my Hyundai Ioniq 2018 model and its amazing.
The light pattern remains the same but the light brightness and distance is increased and the color is awesome!
Also i notice that my auto Line keep assist works better and detects the line better which is a huge benefit.

The installation wasn't easy but with the assist of Headlight revolution i was able to install it easily .
Hyundai last models also have not regular housing type for H7 bulbs so with HR help i was able to find and order housing for the bulb.

Installed in our 2016 Ford Edge. Initially, the bulbs would not come on. After emailing HR staff, they advised to swap the pins on the connector that plugs into the factory plug, as the polarity might be swapped. Using their YouTube video, I was able to easily swap the pin position. The lights fired right up. These lights are extremely bright. We may have been better off with the 35 watt bulbs. We will adjust the beams down a little bit to see if that helps.

I was considering changing my headlight but decided to purchase bulbs instead. Glad I did! Light is 10 times better!

other companies never said can't use LED on projector headlights .HR explained i need HID. It was also nice to be able to talk to someone about my setup .with 2014 Kia i needed an adaptor to holds bulb in.these guys sent pictures even before i received the part so i knew what to look for.Would go back in the future

I really like these lights. Make sure if you have a 2015 Ram you get the morimoto harness. I saw the fine print after and customer service was good enough to add it to my order. Harness was a pain in the ass, but works with no light out indicators. GTR 55W are really bright. I really like the performance I get from these. The rest of the install is easy enough.
