Good morning,
I do not know if you mean the light on the dash or the lights on the mirrors.
I attached the diagrams for you of the lights. The lights are controlled by the body control module which turns them on based on an input from the turn signal switch itself.
Do you have an advanced scan tool to be able to monitor the body control module outputs? This is not a voltage check as the signals are sent with a pulsed modulated signal.
