Hey guys, I replaced the halogen headlights on my 2015 F30 3 years ago; the set of LED headlights I chose is from umnitza & they've been working fine until now. Few weeks ago I've noticed the inner 'ring' on the passenger side is now yellow instead of bright white (it is yellow at exactly half of the circumference). I've attached some pics including the driver's normal side for reference. Any idea what the issue could be? Bad ring? If so, can the ring or its light source be replaced? Circuit issue? Do I need a new headlight?
I'm pretty clueless about electric stuff so any input is appreciated!
