[NB2] Low-beams not working (aftermarket HID setup)
So I've had aftermarket HIDs since I've had the car. I had the occasional bulb go out and have replaced both ballasts at one time or another. But this is a new problem.

About 2 weeks ago, I went to turn the headlights on and the fogs/parking lights came in but no low-beams. I rocked the stalk a couple of times and the lights turned on. This has happened several times since. One time I tried revving the car up a bit and then turning them on and they fired off immediately. I was startin to suspect maybe a low-voltage issue either by a weakening battery or alternator.

Tonight they decided to stop working all together.

Parking lights work.
Fog lights work.
High-beams work.

Checked both headlight fuses under the dash- both good.
Checked headlight relay- it switched on/off when I pulled it while the lights were switched on.
Checked the HID kit relay- same as headlight relay: clicks on and off if I unplug/plug it in with the lights switched on.

I'm at a loss. I would drive to an audio shop and try some new components, but it's too dark now.

I did swap out one ballast- nothing.
Have a spare bulb, but unknown age condition and it's slightly cloudy, so probably bad.
Both bulbs were cloudy/hazy, but how could both go bad at the same time?

replacement bulbs are 15 bux on ebay.
I'd loan you mine but shipping would probably cost close to what the ebay ones will cost.

Lol yeah.

I'm hoping the audio shop that carries HiD stuff will let me try swapping some components with just having to buy a whole kit.

Also check you have 12V going to the ballasts. The relay may click but that doesn't mean that the relay is still good.

That's my #1 suspicion. On my lunch break I'll be running out to get a relay and bulbs.

I replaced the relay (main issue) and found one of the bulbs out at the same time. I wonder if the relay killed the bulb. Anyway, new and two bulbs replaced and all is well.
