HID / Xenon headlight jiggle
 

I am a new 370z owner. I own a '15 sport tech model.
I was wondering if anyone else notices the light from their headlights "jiggle" when going over some bumps. I don't think it's a loose assembly or anything like that. Is it maybe more from the "insides" of the bulb? Are these kind of lights extra sensitive to sharp bumps in a tight suspensioned vehicle like ours? I've googled this issue and it does pop up quite a bit with other cars including mustangs, mercs, audis, etc. It appears to be a "normal" thing. But, I'm suspicious. Let me know your thoughts and experience with this issue. Thanks! :)

My guess is that it is the internal shutter that is moving when jarred. I would notice it every now and then on my '09 Touring. YMMV

This sounds like a reasonable explanation. Thank you! And therefore it is somewhat normal-ish. I'm surprised more people don't notice this. Is there a fix of some sort to make it perfect or is it just the build is less than perfect quality of the actual light itself? In any case, thank you for your feedback. 😉👍

Assuming that it actually is the shutter bouncing around, then a stronger spring could be used when the bulb is made ... but that would require a stronger electromagnet to move the shutter.

Maybe someone else knows of a bulb that is less susceptible to vibration.

Hmm. I'll have to investigate some more. It is rather annoying. Nissan should have used better bulbs OR mine are just not working correctly.
Thanks again for your input - much appreciated! :)

its likely the bulb holder. mine came undone on one side. reseated the bulb and the spring clamps and never had another problem. here's a pic of what i mean by "spring clamps"
