I finally got tired of not being able to see the road at night and decided to go for a LED headlight. Let me start off by saying the schematic from Guzzi doesn't correctly show how the headlight is wired. It only shows the blue as ground for the low beam and power is applied to all bulbs. This is not how it really is.
The schematic should show that blue is ground going to the high and low beam. A brown wire is spliced to the blue going to the parking light.
The LED I purchased has an H4 connector, plus leads for the parking light. However I discovered that when the parking light is activated it actually illuminates the low beam, and when you turn the key on the tail light illuminates along with the low beam so I decided to disconnect the parking light.
To install a new headlight bucket, I had spacers made from 3/4 inch 303 stainless steel. For this particular application the thread to the bucket is M8x1.0 and the holes for mounting screws to the bike are M6x1,0 and the thread depth is 15mm. The spacers were installed using loctite 242 and with jam nuts to prevent them coming loose.
Next came the point of no return. I cut the wires to the headlight with enough left to re-install the stock headlight if it is desired in the future.
Not knowing at the time I would be using the parking circuit I soldered on an extension for it along with an H4 connector. All connections were covered with heat shrink tubing.
From a section of inner tube I made a protective cover for the wiring as the headlight bucket does not have a grommet at the entry point.
Next came mounting the headlight bucket. I mounted the bucket with two M6x1x30 Allen head screws. I also coated the threads with anti seize since stainless has a nasty habit of galling on fasteners.
Last came the step to assemble the ring to the bucket.
All that remains is to adjust the headlight aim. I can tell just be running the bike in the garage this headlight is much brighter that the original and should do well at illuminating the road at night.
