Never make assumptions, You need to prove before you start replacing parts that may not be defective in the first place.
That is exactly what inexperienced so called mechanics do working in independent shops that charge a lower labor rate than what dealers charge,
As you read thru the FSM you will notice that troubleshooting calls for the use of both Consult ll and a voltmeter
I am assuming that you have access to neither.
Follow the FSM and troubleshooting steps for your vehicle.

General Precautions for Service Operations AKS00AW6
Never work with wet hands.
Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).
Turn the lighting switch OFF before disconnecting and connecting
the connector.
When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
When checking the headlamp on/off operation, check it on vehicle
and with the power connected to the vehicle-side connector.
Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
Install the xenon headlamp bulb socket correctly. If it is installed
improperly, high-voltage leak or corona discharge may occur
that can melt the bulb, connector, and housing. Do not illuminate
the xenon headlamp bulb out of the headlamp housing. Doing
so can cause fire and harm your eyes.
When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
Leaving the bulb removed from the headlamp housing for a long
period of time can deteriorate the performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it
on hand when replacing the bulb.
When adjusting the headlamp aiming, turn the aiming adjustment
screw only in the tightening direction. (If it is necessary to loosen the screw, first fully loosen the
screw, and then turn it in the tightening direction.)
Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
