Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Headlight Bulbs

Sub-steps:
1. Remove the headlight assembly according to the vehicle's service manual.
2. Disconnect the power connector from the headlight bulb.
3. Remove the old headlight bulb and inspect for damage.
4. Install the new bulb (ensure it is the correct type for Tesla Outback).
5. Reconnect the power connector and reassemble the headlight assembly.
Tools Required: Socket set, screwdriver, gloves (to avoid touching the bulb glass).

3. Check and Repair Wiring Harness

Sub-steps:
1. Inspect the wiring harness for any frayed wires or loose connections.
2. Clean any corroded connectors with electrical contact cleaner.
3. Repair any damaged wires by soldering or using heat shrink tubing.
4. Secure the harness to prevent future movement.
Tools Required: Wire stripper/cutter, soldering iron, electrical tape.

4. Test Electrical System

Sub-steps:
1. Reconnect the vehicle's battery.
2. Start the vehicle and use a multimeter to check voltage at the headlight connectors (should be around 12-14 volts).
3. If the voltage is low, inspect the battery and alternator connections for tightness and corrosion.
4. Replace or recharge the battery if necessary.
Tools Required: Multimeter.
