A technician performing a vehicle inspection notes that the driver's side headlight is aimed significantly higher than the manufacturer's specification. Why is this a reason for inspection failure?

1. It will cause the headlight bulb to burn out prematurely.
2. It indicates a severe problem with the vehicle's electrical system.
3. It can create excessive glare for oncoming drivers, impairing their vision.
4. It violates federal standards for aerodynamic efficiency.
