That's very strange. My old print manual has the headlight and taillight on P. 50, then the horn, etc. is on P. 52. I've sent you a quick scan of the 175 headlight pages out of my manual. I'll get a better scan to Richard and Scott Noga, including the 200 headlight, which I have as a separate supplement. Maybe someone else can find a print full parts manual that has the lights section included to scan the pages from, otherwise I suppose it can just go on the web site as a 175/200 lights supplement or be inserted at the end of the parts manual that is on the sites.
