Neutral light out

[gcdpetaluma]

Hi, I have a '66 CL77 and looking for tips on tracking down why my neutral light won't work. Yes, the bulb is working. Appreciate any suggestions.
I also have a problem with my tail light. The brake light works fine but the running light is out. Is that bulb a duel filament??
Thank you.

Here's a previous Honda 305 Forum post about the 305 Neutral Switch: viewtopic.php?t=7635334. Next steps would include troubleshooting the wiring harness' continuity, and verify that the neutral switch is working.

CL77 taillight bulb is a dual-filament 1167 bulb.
