Why buy new when you can restore?
Alright, I just sent an email to DDM.
My symptoms seem to follow the "One Side Doesn't Light Up".
I haven't had these very long. I put them in on the 4th of July. And also my truck doesn't get driven a lot at night (maybe 15 minutes 4 days a week if that).
My low-beam bulb on the driver's side has been flaky the last 3 or 4 weeks. I thought it was just a bad connection of the power going into the ballast (since the passenger side was working just fine). So unplugging it and plugging it back in seemed to work. I also put some di-electric grease in it just in case.
Yesterday I turned on my headlights and the driver's side low-beam didn't turn on. I unplugged it several times (approximately 6 to 10) and still nothing. So I unplugged the low-beam bulb from the low-beam ballast and plugged in the high-beam bulb (known to be good/functioning properly) to the low-beam ballast. Still nothing. So then I put my ear next to the ballast and could hear it buzzing. However, it was buzzing at a much higher frequency than the properly-functioning passenger side.
I have a total of 4 of the Apexcone ballasts in my truck; which all functioned properly for 2 months and nothing has changed in terms of the setup or wiring. The passenger side low and both high beams work fine. Thus there is no problem with my wiring. And as stated above, I have swapped bulbs and the problem still persisted.
In short, I'd like a new Apexcone 35w ballast sent to me as this should be covered under the Life-Time Warranty.
Please let me know if this will be covered under the Life-Time Warranty or not.
Thank you,
Matt

Wait, I thought you did your stereo install yourself?
