Hi Davis, Welcome to 2CarPros.
What you describe is likely the DRL (Day time running lights) failing. There is a DRL module under the dash that is basically just a diode. As it ages the voltage drops to the head lights and they flicker. A simple diode test will tell you if it is bad.
Below is a diagram of the circuit.
