The headlight ring on my CB has started to rattle. I have checked all of the mounting bolts and they are tight. Anyone else have the same problem?

Are you sure that's where it's coming from?

Yes, When I press down on the headlight ring the noise stops. I have checked inside the headlight bucket and nothing is loose or hitting the bucket.

Not sure without seeing it, but here are a couple of ideas you could try:

install a little foam tape inside the ring near the bottom to stop the rattle

slightly bend the tab on the ring that fits into the housing slot to make it fit tighter
Now that I think about it, make sure your headlight mounting bracket bolts are tight in addition to the ring mounting bolts (which you said you already checked). Pressing on the ring would also apply pressure on the overall housing which could be loose and the cause of the rattle.

The connectors inside the bucket could also be vibrating against the headlight unit (the thing the bulb goes in). I wrapped all the connectors in the bucket with thin sheet foam and my noise stopped.

Thanks for the ideas. I will try them

Just for info. When mine was buzzing, just about anything I pressed on would make it stop. So unless you are SURE its the ring, pull the headlight and wrap the connectors. Its free and easy. If it doesn't work, well it was free and easy.

Glad I found this thread. My headlight is buzzing like crazy and all of the OP's stuff applies to me as well. Very annoying, as it happens from 3500 to 4500 rpm, and I spend a lot of time in that range.

OP, how did you deal and did it work?

It shows the inside of the headlight shell and the connectors. I also put a pic of some of the connectors wrapped in foam. After I took the pic, I went back and wrapped all of them. No more buzzing. A couple other members tried it and their buzz left too.

The connectors can vibrate against the bucket and the part that holds the bulb, so wrap all of them. Like I said above, it is easy. AND it is free so if you still have a buzz, you aren't out any money!

Thanks senor Popgun! I will dive into the bucket tomorrow.
So... all the connectors and wires and stuff are hidden in the light?? No wonder the front end looks so clean.
