Sounds like bright switch is failing. Or maybe it's just your headlight switch. With the added power from bright lights it might be getting hot and shutting off?

Try kicking your bright switch when it starts flashing. Maybe that will help, or at least show you what is wrong.

There are many threads regarding flickering lights.
The problem stems from the electrical current for the headlights goes through the switch.
The switch contains a breaker & this is what keeps going off.

I suggest doing the Relay system upgrade.
