"I too have a 78' 750K and it looks like you might have different turn lights from an earlier year"
The lights are actually my little contribution to bike's history. They are tail, brake and turn signals all together. My brother gave those to me and they came from a Harley he had a few years ago. Between my brother, uncle and cousins, I'm the lone Honda in a world of Harley's. Some of that influence is bound to show up in this project!

Anyway, I like the look of the dual tail lights.
Thanks for the link industrious Steve-o. It looks like they want me to call for a price. I've seen that same schematic on another web site and they said it was longer available. If it was, the price was over $100.00, about $123.00 if I remember correctly. I can't spend that on a grab bar. I'm talking with another member in the "bike and parts wanted" forum, hopefully that will pan out. If not, I'll just have to be a little more patient.
