A lot brighter than the OEM headlights I had before. Easy to install and overall a great product.

5000k worked amazing. System was slim enough to fit right in the back plate and installed in 20min.

First shipment missed half of my order and the second time it shipped included a wrong bulb. Qc department needs some work.

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

These headlights are BRIGHT !!! I would say by far the best kit I've ever purchased! Customer service is top notch !!!

Have a 2014 Jeep Cherokee. My wife hated the headlights, way too dim! Looked around and found HR. Installed them (very easy) and it is literally a night and day difference!! Very happy, mostly because my wife is very happy!!

Lights work perfectly and were plug and play. They are really bright and a true 6000k diamond white. I have led fog lights and they match perfectly in color. (05 Pontiac GTO)

Had some amazon led in before and these blew them out off the water in every way. Eventually when the bulbs burn out I'll go from 8k to 6k for a color closer to that of the suns.

I have an '18 Toyota Highlander with horrible stock halogen lights. I've been looking around for better lighting options, and initially I tried LEDs for my low beams but they still didn't perform well enough due to the projector lens. The staff at HR highly recommended this GTR 55w HID kit, and I must say it is a vast improvement over anything I had before. I tried different temperature bulbs, but long story short I called HR due to some bulb issues (different colors within the pair, maybe defective pair, etc.). The bulbs I have now are 6000k, and the light output is diamond white with a blue hue. Not only is the output super bright, I love the color because it gives a hint of blue. HR customer service is excellent as they were extremely helpful via email and phone, and they sent me new bulbs within a week. They really want to be sure their customers are happy and taken care of.

Some things to note. The bulbs can run very hot. HR told me stock housings are high quality and can withstand high heat, so I'll be monitoring my lights regularly. I've read other customer reviews and I haven't come across any issues though. My low beams require dust covers, so it took a bit of work to use a cone bit to drill just shy of an inch circle like the HR youtube video shows.

Overall, I am very happy with this purchase. I can finally see well at night, especially when I am well outside of the city. I put LEDs in my fog lights and high beams, but I rarely ever use them anymore because my HID low beams are more than adequate. If you are looking for a substantial upgrade for your low beam projectors, this is the kit to get!
