30a is what I used. Not sure if that's specifically what caused the melting, but perhaps.

Great writeup. I will be installing the 35w in my fogs and 55w in my low beam end of this Month. Just to damn cold to do it now up here at drumm. I will deffinetly be using this.
I would advise against the 35w DDM HIDs in the fogs. They get to hot.........they melted my fog light housings to sh$t. Now I have to buy replacements

Mine started to melt as well. I ended up putting projectors in my fogs and running 35w that way. Otherwise, go with 25w.

I have a Yukon so it will be a little different but didn't know if anyone could answer me this.
Which kit should I get? I would assume on the website that I could get the DDM 35W & 55W Single Hi/Lo Motorcycle HID Kit.
I emailed DDM and they came back with the slim ballast kit, then wouldn't I need the harness? Because that would be around $60 while the hi/lo kit looks like it already comes with the harness for $38

You want a slimline kit, hi/lo bulb will come with all the harness you need, so no need for a relay harness. I'd honestly probably skip on DDM and go get a Morimoto kit on theretrofitsource.com I think DDM's ballasts are pretty good but their bulbs are hit or miss.

I have a retro solutions one in my car and they are pretty good, a ballast just went out on me though so I have to contact them to get it replaced. I paid about $100 for it. For under $50, I can't see much being bad or not the same as my $100 or more. The light color or density might be off a little, but it was only $50 to begin with

Ok so I'm ready to get some HID's for our Yukon. I was going to maybe go with the bi-xenon lo-hi bulbs. The couple that I have seen though have the "shield" thing over the front of the bulbs, or a shield on the side of them. I don't need any shields do I since the stock housing has the one in it? Is this just a bi-xenon thing that it has to have and I should just find some regular lo beam ones?

The shield is there to try to block some of the light, making it go back to the reflectors in the headlight housings to distribute the light. If you'll notice, with stock bulbs you usually can't see the source of the light, only the reflection from the housing. For the Yukon you need a hi/low kit in order to retain hi/low functionality and pass inspection if your state has it. Fyi, hi/low on a HID kit just changes the position of the bulb to change the reflection pattern, doesn't actually get brighter.
That help?

Thanks! I hope it helps some people out. I don't personally have them on my Tahoe anymore due to a few equipment violation tickets. VA is pretty **** about car mods unfortunately.

Ok I asked the seller and he has the shield picture was a H4. I went ahead and got the h13 hi/lo kit. Now I have a real tech question. On my regular bulb the back filament was burnt out which was when I clicked over to hi beams. So I would assume that was the hi beam filament. But now with my hids would it change?

HIDs don't actually get brighter when you switch to high beam. The bulb's position itself is changed to make the beam shoot higher.

Well yeah they are the bi-xenon, so the high beam is a halogen part. So if they are backwards (like I suspect) then when we turn on the high beams they would actually be the "low beams" and look brighter because its actually the HID bulb instead of the halogen. Do I just need to try and flip the connection, I am guessing its wired wrong.
Also what way should the little bar be at? On my accord they are pointed down

Ok so I really took it apart and looked at it right now. I hope someone can answer me before I have to put it back together in a couple hours.
When I click on the hi beams, the bulb moves out and when in low beam its in. I hope that makes sense. Also the wiring harness I have, if your looking at it where the place that it clips in the wires go white, black, blue. Maybe I need to switch out the blue and white because it seems like its backwards to me.
When I turn the high beams on, the headlight level goes down and when I flip them back to "lo beam" the light pattern raises, so that makes me think they are backwards.
PLEASE HELP, the vendor is not helpful at all

It sounds like it's backwards then. When you switch to high beam the level should go up. The bulb does indeed go in/out for hi/low, one way focuses the beam more and aims it up a bit for hi and the other is the exact opposite. Hope that helps.

Yeah they are backwards. I looked up the wiring for the stock socket. Then found a site that had what the blue and white were for the HIDs and they are indeed backwards. The vendor sent me a new harness and that one would of been backwards to, but it has 2 little boxes that is suppose to stop the flicker when they start up. Only problem is that they sent the harness and then an extra 2 little things and said I should know how to attach it.....um nope the harness I understand but not the other

Did you use single or dual relay? Error eliminator or adapter cables? I am about to place an order and these options I am not sure what to select. Thanks!

I just used the relay harness from them, so I'm not sure which it was.
