Mitsubishi Montero Sport headlights inoperable, possible alternator and relay issues on Mitsubishi Montero Sport

Some Mitsubishi Montero Sport owners report experiencing inoperable headlights due to various issues, including alternator and relay problems. These owners note that a faulty alternator can lead to dim or flickering headlights, as it may not provide sufficient power to the vehicle's electrical system. Additionally, issues with the headlight relay, which controls power to the headlights, can prevent them from turning on altogether. Damaged relays can cause malfunctioning headlights regardless of bulb condition, and replacing a defective relay often resolves these issues. Owners are advised to inspect the headlight relay for damage and check related fuses for wear or corrosion, as these could disrupt the circuit to the headlights. If only high beams are functioning, it may indicate a relay problem, and swapping it with an identical relay can assist in diagnosing the issue.
