Round headlights

[Rasputin]

The bold part is probably the part that matters!

I put them on so that the longer part of the tube was on the bottom so that the light sat as high as possible.

And yes the 5/8" is just about right for trimming

I also used slip joint washers (used in plumbing) on the top and bottom of the tubes to hold them steady and centered on the fork tubes. This though also effectively killed any chances for the ground circuit that used to be there so I had to run a separate ground for the turn signals.

Damn. I just noticed that I have installed mine upside down. Looked at the pic of the LH available here on the ads/brochures selection and yup the long part goes to the bottom. Good thing I do not have all that much to tear apart to switch em at this point. Your conversation in this thread just saved me some time. Thanks
