uh oh, no low beams!!!

So went and fired my truck up this morning and released the e brake and normally my lows start to heat up (HID) but only my turn signals came on. So I checked fuses and were good. Bypassed harness for HID's but nothing. Swapped low beam wire over to high beam. Didn't even turn those on. High beams and fogs work. So for right now I swapped my high beam harness to my low beams and have to turn on my highs when I want my lows haha.

Any ideas? I also replaced relay and nothing happened as well. This is kind of really important considering I drive to work at 430-5 in the AM

Relay, fuse, ballast, bulb, wiring. All those should be checked

Checked everything except wiring. Could it possibly be the switch on the dash?

Replaced switch and that did nothing. Already had one laying around so it's not like I wasted my money or anything. So I moved on to a couple other things...

 

Didn't realize I had an inline fuse for my harness for my HID's (so they warm up faster). Checked that and it fell apart! So I replaced it but it didn't do anything. So I just completely bypassed that harness and plugged the low beam directly into the HID. Boom! It fired right on up! So now I either have to check for a short in the harness and possibly rewire it, or just remove the harness altogether. My HID's are DDM tuning HID's so not the best quality, and so is the harness, so maybe something came loose up near the relay or like I stated before, there is a short somewhere.

 

What kind of HID's do yall have out there that are pretty quality built?

None on the truck ('07 900 series), as I found the lighting on that to be the best feature of it ... but we threw a set on our '86 Grand Marquis. A little different than the 9006 or H11's of the 800/900 trucks being an H4, but the components to activate and run them are the same (minus the high beam). As we expected, it was a literal night & day difference in light output over the sealed beams.

 

Don't know what the specific brand of the kit is, but I bought them here: http://www.coolbulbs.com/HIDKits_body.asp

 

The place claims that these are the exact same units used on the high end German cars. We only drive the Marquis in the summer, but these lights have been on there since November '12, and have worked flawlessly from the frigid single-digit to below-zero New England winter to the 90° summer days at 75% humidity we've had the past week.

 

Here's a couple pics of the components where you can see the manufacturer's logo:
