Hi all,
I recently had an issue where the drivers side dipped beam would work sometimes and not others. It was an HID light that had been fitted for at least 5 years, sometimes turning the lights off and back on a few times made it come on. And once it had initially come on, it'd stay on for the rest of that journey.
I got fed up of it, and was told it could be a dodgy ballast unit, so I ordered a new set and fitted them a few weeks back (about 3 days before they announced the intended MoT changes), and all was well. That is until the start of this week, left for work Sunday night and had the same issue, drivers side headlight wasn't working. I tried turning it off an on again at least 20 times, including stopping in a layby, turning off the lights, and then ignition, then restarting the car and turning the lights on again, but it just wouldn't work.
I came out to go home at 6am Mon and both lights worked right away, and stayed on all the way home. Worked ok Mon night and Tues morning, wouldn't work Tues night, or Weds morning, worked ok Weds afternoon, about 3pm, but Weds night and Thurs morning, not working again.
Now what are the chances that the new ballast has gone dodgy within a few weeks, and just happens to be on the same side? Or is this more likely to be a wiring problem to that headlight? Also, could the ballast be affected by the cold? They've been mounted in different locations each side, and the only pattern I can see seems to be not working when it's below about 2 degrees.
Any suggestions of where to start looking would be great, thanks.
