HEADLIGHTS GO ON AND OFF WHY?

2001 Suzuki Van • 85,000 miles

After driving awhile the headlights go off both high and low beam. Turn signals still work. Lights come back on after about 40 seconds.

It could be a faulty relay or switch.

Could it be a voltage regulator?

No, voltage regulator faults would result in battery draining and affects all electrical components.
