I will see what I can do over the weekend in looking into this on my 1750. I know that there are two screws through the crome part of the light housing, can't remember if the bulb socket is then screwed in or twist or what. Had mine apart last year to clean and polish. Took an old tired looking unit back to near new, with the exception of very minor pitting in the chrome itself.
