Condensation Inside the Headlamp: Moisture buildup within the headlight lens can reduce visibility and may indicate a seal failure.
Bulb Burnout: Headlight bulbs may burn out over time due to regular use.
Regular inspection and maintenance of your vehicle's headlights can help identify and resolve these issues promptly.
Regular Cleaning: Keep the headlight lenses clean from dirt, debris, and grime using a soft cloth and appropriate cleaning solution.
