Answer: You must check all your lights often, and promptly replace any burned out bulbs.
Step-by-step explanation:
The different vehicle lights are used for different purposes in the vehicle. For example,
Headlights: The headlight produce low and high beam of light. These lights allows the driver to observe the road in the dark.
Tail lights; These are used to produce the red light at the rear of the vehicle. This helps the driver driving behind the driver to measure the distance behind you.
Fog lights: These are mounted near the headlight to see through the fog.
Signal lights: These are the blinkers the driver switch on these light while standing on the signal or while taking a u-turn.
All these lights have specialized functions in the vehicle thus these lights must be checked regularly. The bulbs of these lights must be replaced when burned out.
