The headlight bulb sockets ground to the headlight bucket which grounds to the headlight bar which grounds to the frame all through the bolts that hold everything together. Similar for the taillights. The current runs from the light switch through the wire that enters the light socket at the bottom and then through the bulb (causing it to light)and then to the light socket that is grounded. Take the bulb out and test between the pin in the socket and the ground with the lights on, you should have about 6 volts. If you really want to measure current flowing to the bulb they have test equipment you can place over the wire to do that but it is not commonly used.
