Okay, they need to verify powers to the light module as well as the BCM.
I would remove the bypass and hope there is no damage to the modules and have the wiring issue checked by someone who knows what they are doing.
You need to start at the headlight switch and work your way out to the lights. Tests for power with a voltmeter or test light are needed.
They need to follow the diagram that I sent you to find where you are losing power.
