    No return wire shadow.
    No relay, thus no relay buzz.
    No TPMS error after 25 minutes of operation with lights on.

    Based on my experience, if you install without relay and without CANbus harness, the end result is once the car's started the lights will flicker out. With only the relay, the relay will BUZZ because the CANbus is sending signals to the headlight that pulses at a relatively high frequency, causing the relay to rapidly open and shut. Relay with capacitor fixes the problem, but an unshielded ballast can cause TPMS errors after the light has been on for more than 25 minutes.

    The BEST solution is a stand alone CANbus harness, since the headlight connection is capable of sending enough current to drive the light. A relay harness is not needed. In combination with a shielded ballast then the system works just fine.
    Interesting.

    I've been debating whether or not to go Diode Dynamics or TRS, this is good to know.

    Any noticeable issues or is it still working just fine?

    2012-13 Veloster Diode dynamics HID relay buzz fix from DD!!!!!!!!!!!!

    So, yesterday I purchase the 6000k diode dynamics HID kit which I went & picked up here in Saint Louis,MO.
    Derrick @ DD was super knowledgable and really helpful. I bought the kit and some stage 1 LED turn signals for about 155$ total. Went home,installed the kit, and once I started the car, the dreaded "relay buzz" I read so much about on about 50+ forum post on several different formats and vehicles .

    I called DD and even though it snowed 6 inches and it was Sunday, someone still answered the phone and it was Derrick ,on a SUNDAY @ 11Am , awesome! So I drove over there, he let me pull the car in the garage and before we took the whole car apart , Derrick suggested we try a warning blocker(resistor ) they sell for 5$. Literally ,it was plug and play ,and fixed it in literally 2 sec. Really quick and extremely easy . I give this place and A+.

    The Retrofit Source relay kit uses two relays, one for each ballast. The advantage being that a single relay failure does not knock out both bulbs, only one. I will be installing one of their kits together with their Morimoto Mini projectors soon.
