What should a driver do if the right-hand headlight bulb fails when driving at night?

Drive with the hazard lights on.
Have the bulb replaced immediately.
Replace it temporarily with the left-hand headlight bulb.
Replace it temporarily with the brake light bulb.

Explantion: Vehicles (except motorcycles) are required by law to have right and left headlights. Faulty lights should be repaired immediately. A vehicle with only one headlight can cause a hazard to other road users or be mistaken for a motorcycle.
