You can rule out a number of bulbs with a few simple steps.

Start the car. If the indicator is NOT on, then turn on the headlight switch. If the indicator comes on, then it's one of the bulbs activated by the headlight switch (including the license plate light). Many bulbs to investigate here including the parking bulbs. BTW, cockpit lighting does not affect this system.

Shut the car off and restart each time to clear the system. Sometimes the indicator will not turn back off with the different steps.

Depress the turn signal stalk either direction or switch on the hazard switch. If the light comes on, you can narrow it down to which side. Sometimes the indicator comes on and off in this situation.

Tap on the brakes. If the indicator comes on, it's the brake bulbs in the taillights OR the third brake light (most of us forget to check that one).

Put the car in reverse. If the light comes on, then it's one of the reverse/back-up bulbs.
