1980 Honda 185 head and tail lights out

[HamptonT]

Checked bulb and its good. Checked connections and don't see any issues. Anyone out there have any advice?

The headlight switch itself could be bad. Or lighting coil may have gone bad. You can download the manual here: http://www.oscarmayer.net/atc/manuals/

Page 14-2 tells you what wires to test to see if the coil is good.
