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!

got lights unable to mount ballast in housing call support no issues said they have extension cables ordered them

This product is fantastic in it's ability to produce a super bright output. I will be purchasing conversion kit's for our five other vehicles in short time. Great quality and design by the engineers and that's tough to say when I work with engineers all day and I know how big their ego can be. Never the less, GREAT JOB ON ENGINEERING THIS PRODUCT!

Awesome lights, heaps brighter than my old HID kit.

Were on back order when I ordered them but well worth the wait. I have had a few different brands and these are amazing. the cut off line is precise and clear. Exactly what is sold is what you get. Worth the money. I don't often write reviews but you can be assured you will be happy. Install was easy. I watched the video produced by headlight rev on how to install with dust covers beforehand.

My vehicle was wired wrong and had to request help and they sent cross over connector to make it work. These are what should have been on the suv ;before I got it.

I made the plunge to upgrade and so far I'm glad I did. Installation wasn't a problem and the quality of the materials is impressive. Installed the 55w hid smart PWM slim kit. The output of this kit put my previous installed Osram Nightbreaker Unlimited bulbs to shame. Awesome customer service and they stand behind their product.
Glad I didnt experiment with cheap kits.

First off let me start initially by saying i'm an over the road truck driver I've tried a lot of kits and a lot of leds and a lot of H IDs however headlight revolution knew what I wanted and gave me what I wanted. I ordered the GTRH ID kit 5000 color and had them overnight ship them because I was rolling out for a three month freight lane in 3 days However I noticed I hadn't got confirmation yet that they were shipped so I called And the 5000 K was out of stock I was a bit worried so they ship me some 4300s overnight delivered 8 o'clock in the morning just to get me on the road and they would send me the 5000 K when I was ready and I could keep the 4300 as a replacement because of the miscommunication and error. Another little mishap was one ballast went out and I called and they would send me another ballast overnight anywhere in the country. This company is one of the top companies in my book when dealing with lighting and customer service

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
