HID Relay Harness Problem

Question about HID relay harness:

Today my headlights just won't work. They are Mini H1 retrofits with DDM Tuning HID kit. At first I thought it was a grounding issue, but neither headlight would come on.

So I then kept messing around, grounding it to all different areas, and nothing. Only thing that would happen, is it would flicker ever so slightly, not a full brightness.

I can't figure out what's wrong. I'm assuming the relay harness went bad, as it's from eBay. Anyone have any suggestions to try? I'm going to try a friend's relay harness tomorrow.

I'm not actually sure if it's the relay harness or not.

There was an article, I cant find it, but it is about the internal quality of cheap relays. Replace it with a quality one.

Ah, yeah I tried searching around briefly.

I'm going to try a friend's relay tomorrow, if it's just that, I'll be happy.

Just wanted to hear opinions.

Money its the relay. Did it get wet? One thing I learned with DDM, any HID kit for that matter, they need to stay dry, and that can be tough. I don't know how many ballasts I replaced so far, a lot. I am on my 3rd relay harness I believe too.

I had a **** relay too back in the day, so I just took it up. Getting a new quality one as we speak.

Relays are DEFINITELY one of those things that you get what you pay for. Getting a cheap one will end up having you spend much more money in the end. Get a good one.

Xentec kits suck. Last a couple months at best and when you try to use the warranty they offer they pull a MKulrey and never answer you.

yes however its not a good idea to do so. the relay harness prevents the stock wiring from melting

Well I thought about it, but from what I've been hearing from various people... the quality of the eBay harness is just awful (I expected it to be bad, but not to stop working after a few weeks).

I recently sold some stuff on eBay so I had money in my PayPal account, so I just ordered from TRS. Whatevs.

So I guess the point of this thread now... don't buy eBay relay harnesses.

that's because DDM kit is $29.95 for the complete set and $9.99 for a harness. That's 39.94 plus shipping.

and TRS kit is $150 plus shipping, harness of your choice included.

You get what you pay for.

It's like saying "Chevy Cruze sucks, Stingray does not".

It's not really "apples and oranges", it's more like "leftover apples at the farmer's market" and "premium organic hand grown select apples"

The ballasts.
They arent sealed.
They did not get wet but since they were sealed condensation got inside and corroded everything inside. This happened with 4 of them.
