Hello first time member here and I am having issues with my HID kit for low beam in my 2014 none projector. My driver side headlight does not come on it started about a month ago(installed the kit in May). I used to be able to flick the lights from auto to off and back a few times and would come on but today no luck. I would appreciate any help.
Usually this is a result of either:
A) Some HID bulbs have quality control issues where the amount of mercury or gas pressure inside the bulb is not consistent between bulbs. This can make the HID bulb very hard to start or ignite. This puts excess strain on the ballast as well. Some ballasts have an over load safety feature and will cut power to the bulbs if its pulling too much power for too long. Resulting in a non-start.
B) Ballasts are not getting enough electrical power. If the ballasts have to work hard to pull in current, this also causes stress. If the path to ground or incoming power does not have sufficient wire thickness, or low path resistance, it can cause ignition issues.
C) Premature electrode wear. For one reason or another, if the spark gap in your hid bulb is too large, or has increased over time due to electrode wear, it can cause this effect as well.
Sadly Both cases A and C can cause the ballasts to fail prematurely as well in our experience. So if the bulb was the source of the problem, it may have caused damage to the ballast as well. In which case, replacement is the only option.
