The left lamp of the turn signal indicator is connected through an orange-white, the right lamp through a brown-white wire to terminal 5 and, respectively, 6 of the alarm switch and there from terminal 4 to terminal 5 of the turn signal lever switch. Thus, each indicator lamp receives a positive electrical charge from the turn signal switch and flashes in the same rhythm as the turn signal side is on.
Even with burnt pilot lamps, the light relay continues to operate normally, but the lamp should still be replaced, despite the relay ticking audibly.
