headlight vibrating after installing a extender for fairing
aby suggestions on fix this? it's a 2019 48. it's a below light mount. I added a extender because of the burly brand fairing I got. it's a rectangle pice of flat meter that brings light forward about 2 inch. but now my headlight vibrates pretty bad, I did tighten pretty good. has anyone run across this before?

If you can move the light with your hand and see that thin piece of metal flex then your light will vibrate. As said above get a piece of 1/2 inch thick Aluminum Bar stock at Home Depot or Loew's etc., cut it to length, using the thin piece as a guide and drill the mounting holes.
File the corners round.
It may still vibrate but not as much.

Can you have an extender plate made from 10 SWG (3mm thick) stainless steel?
If you aren't familiar with SWG, it stands for Standard Wire Guage.
That plate you have installed only looks like it's 16 SWG (1.5mm thick), no wonder it is oscillating, it is supporting a lot of weight there.

Maybe some large flat washers under the nut and on the headlamp would dampen the vibration. Spread the load over that thin extension piece. Sandwich it in with washers, use some blue Loctite.
Maybe just a couple fender washers above and below that rear nut would stiffen it up. You can grind off any excess.

What is the dimension of the gap between the headlamp mounting lugs?
I have seen aluminium block that you could make a single piece that would mount using the original screw and also hold headlamp.
