wtf are these and no headlights

[trkklr77]

these are on the upper right hand corner of the fire wall. they were wired in with the externaly reg alt harness. i redid my wiring today to mod and move the alt to intr reg and the p-side of the motor.

instead of looping the external reg plug, i eliminated it. i used a small alt harness for a 73+ that had the main power, ext excitor, and the brown wire back to the fire wall, it is charging the batt and powering everything but the headlights.

i dont think they are related but ???????????
