Last week I noticed the passenger side head light of my 2016 300s was out. I ordered new oem Philips xenon bulbs. My husband changed both bulbs so they both light up the same, he wore gloves & didn’t touch the bulb when installing. Well 4 days later the same passenger side bulb went out, the driver side is still working with no problems. We put the old bulb that was on the working side on the side that went out, however when installing we noticed it was flickering on and off. My husband was adjusting & playing around with the wiring behind it until it eventually stayed on. Well next day the bulb went out again. I’ve noticed buzzing/humming prior… when the light was working, not sure if that’s normal. Do any of you have any idea what could be causing the bulbs to burn out? We’ve checked for headlight/lamp damage but we don’t see any cracks or anything. The dealer is charging me 160 just for a diagnosis so I’m trying to avoid them of possible.
