I've got a headlight issue on my 2009 Mazda 3 - 2.3L. The vehicle has the auto headlights.

When I turn the car on, turn the headlights to On (not using auto), sometimes the left low beam light doesn't come on, but the right one does. If I turn the lights off then back on again, they can both come on. Sometimes neither of the low beams come on, or sometimes they both come on, then turn off shortly thereafter.

The high beams and fog lights all work normally.

I've checked the fuses under the passenger side dash, and they are fine. There's a 40amp fuse that manages all the headlights under the hood, but that seems fine. I cannot find a location or even correct info if there is a relay anywhere for the low beams, I assumed like some videos show it, they may be in the engine fuse box...but not mine.

So, I am not sure what this may be. A switch or relay....or is it possible the bulbs are overheating? I have no clue, so any help would be appreciated.

Thanks!

 

Do you have HID or halogen lights?

 

I have HID headlights.

Parsing through this forum, I'm leaning towards this issue being a ballast or ballast ignitor issue....
