What problems can be caused by faulty Bulbs?

Bulb does not light up

The bulb does not light up when switched on, other bulbs around it seem to work ok.

Headlights are less powerful than usual

The headlights don't seem to be as bright as they were, they don't light up as much of the road ahead as they used to.
