A little help please...

I'm spending a lot of money on parts for my pig but one of the places I would like to be frugal is the headlight. I don't ride a lot at night and I think I can get by with the stock shell.

I remember reading a couple of years ago that the plastic lens could be upgraded to glass and the bulb could be switched out to a 35W low and a 35W high beam.
Does anyone know the part numbers and have the directions for such a swap?

BTW, don't get upset if you see this question on ADV as I'm going to cross post to get as much input as possible.

I did a search because I vaguely remember it discussed here...Maybe this will help - Headlight Upgrade
