I finally got a chance to install the kit I purchased from DDM the other day. I picked up the 55w 5000k for my headlights. I used the relays that was supplied and connected everything. After the install, there was a buzzing coming from the relay. Slight flickering. No buzzing come from the balasts. I checked everything today and all is tight. This all happens as soon as you turn on the headlights in low beam with the engine on. You don't hear it when the engine is off only with engine on. It's loud enough to slightly hear it inside the cabin. I did not use the error code eliminator.

Does anyone with experience have any ideas? Thanks.

 

Buzzing is normal for magnetic ballasts. If you want it gone, you need to replace with digital ballasts.

 

The ballast are the digital slim version. The buzzing is coming from the relay, not the ballast. So this is normal?

 

If you use the the factory positive or ground to to run relays for axillary lighting the relay will buzz (turn on and off really fast) This is due to the CanBus system in the jks that sense if a bulb is out. This is a pulsed electrical DC system the jk use. You will need to install a canceller or a 220uf capacitor in parallel with the harness.

 

I called DDM tuning and they said the same thing. I would have to install a diode and capacitor on the low beam wire and as well as the high beam.

Now my question to you guys with experience, since I need to install two sets of diode and capacitor. One set on the high beam and one set on low beam. Will this be safe or problematic?

 

I installed the diode and and capacitor on both high beams and low beams. Got rid of the buzzing and now work perfectly!
