Sounds like your ballasts weren't getting enough juice. Get a harness for those HIDs and save yourself the headache.

Wire them with a relay, like so:



I don't trust stock wiring for anything but stock headlights.

All about that unibody life.

The DDM HID kit only uses the stock harness as a trigger, everything else is run through the battery. I have them installed in some E-codes and it's literally like day and night vs my stock lights. Aiming them is the only difficult part. Took a few tries to get the drivers side right.

As much as I hate it. I actually have to agree with xpress here. I would run each light on its own relay since wiring them in series will give the second light less power and could make it dimmer than the first.

Or use a dual 87 relay.

Won't work that way. You'll need to switch the main power regardless if you only use one relay for high and low beams. And you don't want to switch the main power.

The diagram Xpress posted has the headlights in parallel off of the single relay.

Use one SPST relay as your "ON/Off" relay, and use a SPDT 87/87a as your high/low relay. Simplest and most straight-forward way of doing it. If you want to get into dual 87 KC relays, you'll still need the first two switching relays as well. Apparently the new HID ballasts don't pull so many amps so running one relay for both lights is doable.

You can use one dual 87 relay for high and one dual 87 relay for low to avoid running them in series and starving the downstream light. Utilize the factory wiring to trigger the high and low relays

They're not running in series, they're running in parallel. Nothing's being starved in the diagram above.

That diagram looks to me as being wired in series. Eithier way I would do a relay for each light max power available for them no matter what and if one fails you don't lose bothights. Redundancy is a good thing when it comes to safety equipment. I will admit I am not the best at reading wiring diagrams but I am learning. If I read it wrong please explain where I went wrong so I will know for next time

I have my headlights rewired with relays. I utilize the factory headlights wiring for high and low to energize the appropriate relay. Factory low activates my low beam relay and factory high activates my high beam relay. I used dual 87 relays to ensure one side didn't starve the other.

The red wire goes to both headlights and branches off. Parallel.

If it were in series, the red would go to one light,the negative for that light would go to the positive of the second light, then the negative of THAT light would go to ground.

And two relays to troubleshoot are much better than four. This "starving of lights" **** needs to stop. Spreading misinformation based off of your lack of understanding of electrical systems. If a pair of lights is running in parallel, they're both getting full voltage, as long as the relay can handle it. Two HID ballasts are 6-10 amps each on startup. Most relays are 30-40 amps. Enough to run three or four HID ballasts on one prong. I wouldn't worry about a relay failing from high amperage.

Another thing to think about with running high and low off of separate relays: Let's say your high beam relay "sticks" on. You now have juice going to both your low and high beam wires in your lights. If your two-relay system relays fail, either your lights stay on full time (then you replace your SPST relay), or your high beams stay on (then you change your SPDT relay). You're not sending juice through every wire. Having two relays instead of four (you still need the SPDT relay to switch between your two dual-output SPST relays, and the first SPST on/off relay to power the whole spiel) is just a waste of time, energy, space, and money.

Not to mention the limited sources for those KC style dual-output relays. As opposed to 2 bucks a pop for the standard SPST and SPDT relays at some vendors, you're paying $6+ per KC relay. And you're going to want spares.

Where are you getting 4 relays from. I had said two. Don't ***** at me because you assumed something that I didn't say. I even specifically said a post or two ago two relays. The holier than thou attitude needs to go. I also specifically said wired in series which would do exactly what I said it would. No misinformation there. You wire in series you get a voltage drop which will starve successive lights for voltage. So I read the diagram wrong so be it. I stated I read it in series. I didn't say use 4 relays and I didn't say don't wire it in parallel. Read before chastizing someone. It just makes an *** out of you. I made 1 mistake but was specific about the way I read it incase I read it wrong. You however made a bunch of assumptions about me that were wrong. I understand how a circuit works. That should be obvious. What I am not good at is the diagrams. So again lose the attitude. I gave no misinformation. I am sorry you feel the need to twist my words so you can feel superior but you can try that on someone else. There is also more than one right way to do most things. Just because it isn't your exact way doesn't make it wrong.
