Headlamp has a mind of it's own...

The headlamp was not working properly so I replaced the headlamp plug thinking it would resolve the issue.

Did not fix it. The headlamp works about 50% of the time and it fluctuates a lot. The moto runs well and is not affected by the intermittent headlamp. Could it be a bad handlebar switch? If anybody here has dealt with similar issues please help me out. Let the trouble shooting begin! Thanks!

I had a roach coach pull out in front of me one early morning while going to work. Just about flipped him off when I noticed the headlamp was out. Turned out to be the connections in the headlamp- headlamp plug, where it goes to the bulb and the ground connection. I cleaned the connections up as best I could and used some di-electric grease. All's well now, though I'm always checking.

I'll open the headlamp and make sure everything is connected properly. Thanks for the info and be safe out there!

Could it be the reserve lighting device acting intermittently? If you wanted to check it you can bypass it for a while to see if that cures it. Read this and bask in the wisdom of those who have gone before us. Maybe this will help. Have you got a wiring diagram?
