I also have HIDs. & they would intermittently come when while testing them in my garage & looking at the wall to see the reflection of whether or not they would come on. So, I removed the headlight housings & tried a few old school 9007 bulbs that I have in storage just in case. Sure enough, they lit right up.
Next, I wanted to inspect the HID ballast, relay, & bulb connections. All seemed visibly okay. One of the two connections to the ballast looked like it had some corrosion on the pins. I took a small file & cleaned that sh*t off & inspected everything else. I also cleaned the two ground connections (I just use the center-most bolt of two 10mm headlight bolts on each headlight to ground them - that's a pretty good place to ground them as long as you sand a small shiny spot of the chassis under the 10mm bolt washer).
I put the HIDs back in & they seem to work fine. Still experiencing occasionally the passenger side one not coming on but if I manually flip the headlight switch off & then on again they both will usually come right back on. It might be the ballast going out. I just looked on eBay. A replacement Zenex 35w ballast is like $27 w/ free shipping. I've had the same kit in since I think 2010. Zenex out of Florida makes SUPER good quality stuff & they always stand behind their products & their warranty. I have both Zenex headlights & fog lights. 6000K for both. They're awesome.
