    I have never needed to use relay harnesses in the past but due to the new technology in my 2012 Sonata, it was highly reccommended. I bought one for the low beams as well as the fogs. I only wish the lengths were longer especially for the foglights. (Posted on 1/27/14)

    My lights were dimming with just the regular harnesses that i got for my HID's. So I got this harness that DD recomeneded. It worked exactly how it was supposed to work. My HID's fire right up and don't cut out at all now. Great product! (Posted on 8/1/13)

    Arrived in great time, like Diode always has for me. I ordered the universal relay. Install was dead simple. I chose to attach it with my low beam HID kit 8000k for my forte koup. The lights start right up and charge up nicely. There is no flickering like i have seen with other brands before. I haven't had them cut out on me once yet. No dimming or changes with electronics at all. (Posted on 6/11/13)

    Bought a high beam his kit from another company not knowing a relay harness was not included. As a member of a car forum, DD received high marking and customer service. Bought my relay harness from DD and no problems. (Posted on 1/29/13)

    Installed in my 2013 Altima, because they used very small gauge wire, it was almost too short to reach the passenger side but after some PITA routing it was perfect. Thanks (Posted on 12/17/12)

    Very solid product. I received this product originally with an issue in the passenger side plug. The passenger side plug had no electricity coming to it and with a very quick turn around i got the new harness and it works great now. (Posted on 9/23/12)

  10. Just a Precaution. Review by Frank

    I ordered one of these with my HID kit and everything came as expected. The male/female ports matched my HID kit perfectly, though the explanation on how to hook it up eluded me. Luckily, the HIDs work without the relay harness so i was advised: "if it ain't broke, don't fix it." So far so good. (but it's good to have it on hand just in case) (Posted on 9/19/12)

    gives a reassurance that your hid's will work properly for a long time and wont be affected by voltage drop in your battery while running large sound systems ;) . but i would have to recommend having longer relays for those fog installs. the length from ballast to ballast is long enough, but it can use length when trying to reach the battery. some extensions were made and product worked great.

    This was very easy to install, and since its pulling power for the HID's from the battery instead of the electrical system, you do not get dimming lights when using accessories inside the car. This kit will also help protect your electronic system in the event of a short, as it has an inline fuse wired into it. (Posted on 3/24/12)

    The relay harness works perfectly, it was just a little short for how I wanted to run it in my car. I cut and spliced in some extensions. 10 min install. Fast shipping. It just works. Thanks Paul. (Posted on 3/3/12)

    I purchased this Relay Kit after I blew the stock fuse in my fuse box. The Relay Kit has a much larger fuse, and definitely is a great investment, and will save you a lot of time in the long run.

    Than you DD! :) (Posted on 2/27/12)

    I bought a low beam HID conversion kit for my 2003 Tiburon about 2 weeks ago and i installed them with a relay....they have been performing PERFECTLY and I love them....well a few days ago I received my foglight HIDs and installed them...i did not get a relay with them because I had heard that u dont need one for Tiburon fogs because the console does not reset when u switch them on like the lows do without a relay....well switching on the fogs resets my console everytime...its only a few seconds then it goes back to normal and the lights work fine but i want it not to do that so I added this relay and it fixed that problem and now my whole HID system is running perfectly...Diode really makes quality products!!
