One of the common causes we frequently encounter for the malfunction of low beam headlights, while high beams continue to function, is a faulty headlight relay. In essence, relays serve as electrical switches, and both the low and high beams have their dedicated relays.
Some vehicles require simply replacing a bulb, while others might need an entirely new headlamp module when a light is damaged or burns out.

Touch the multimeter probes to the two contacts on the headlight bulb's base where the wires were connected. The multimeter should display a resistance reading. A reading of infinite resistance (OL on the display) indicates a broken filament and a faulty bulb. A reading close to zero resistance indicates a good bulb.
Your headlight high and low beams have separate fuses, so if either fuse blows, that light will go out. Each headlight also has its own built-in relay switch. Relays are meant to last for ages, but over time heat, resistance and constantly switching on and off can cause them to fail.
