Default burning headlights

Anyone have as bad of a time with headlights as me? Sometimes I don't get 10 miles before they burn out.

Triumph unit 500. Sees over 8k and triple digit speeds every time it gets out.

Dynamic balanced, no noticeable difference. Don't recall the balance factor can look it up later.

4.5" bates, can't even find decent sealed beams in production, been through some expensive nos bulbs that lasted a few hundred miles, modern replaceable bulbs, and random screw mount single filaments. currently running an led that pisses people off and I still can't see shit, but it stays on(even that is starting to act like its shorted internally).
Really want to keep 4.5 and not go to 5 3/4.

Added top mount to headlight, no difference, leather washers top and bottom, no difference.


Running a battery and boyer power box, previously ran boyer light delay and no battery, no difference.

New stator and rotor.

I wouldn't expect it , been through the two different boyers, purchased Probably a year apart from different suppliers, the current one direct from the company.

I had a similar issue with my Triumph's headlight. Make sure that your grounds are solid.
I thought mine were but after redoing them the problem went away.
Good luck

+1 on the grounding, and make sure you're grounded to the frame and not the front end. Grease covered neck bearings aren't the best conductor.
