Sturmey Archer GH-6 dynohub magnet upgrade?

Should be lots in the candlepower forums to help the original poster.

I'm sure you'll find methodology to follow for adding LED's to your vintage headlight as well as alternatives.

Hopefully the search engine will help.

The headlight I used for incandescent on my Moulton APB was much heavier and larger than my LED headlight and it was hard to find something that approached the "magic" of the old switched headlight that was "new" I imagine compared to the original Millar or Schwin style



My upgrade was diminutive by comparison but superior for actual usage
