3. Pull off the road as soon as you can and leave your hazard lights on so that other cars can see you.

How does a vehicle lighting system work?

Most car lights work through halogen bulbs. These are anti-glare and are built into plastic casings. This allows them to easily reflect out so that you can see the way ahead of you, and so that other road users can see what you are doing.

Why do US cars have red turn signals?

Studies show that amber turn signals reduce accidents, yet most signal lamps on the rear ends of North American automobiles, trucks and trailers are red. Why? Because amber’s not legally required, and it’s simpler and cheaper to use red for all rear-facing lamps.

Why are they called passing lights?

Dipped-beam (also called low, passing, or meeting beam) headlamps provide a light distribution to give adequate forward and lateral illumination without dazzling other road users with excessive glare. This beam is specified for use whenever other vehicles are present ahead.

How are the lights in a car controlled?

In many vehicles, the light sources are controlled via pulse width modulation (PWM). This has several advantages for the vehicle lighting. For one thing, the same bulbs can be used for different functions, and the service life of the bulbs is increased. The rear lamps of the Golf V also use PWM.

What causes problems with lights in a circuit?

Problems with a single light are usually caused by a burned-out bulb, while problems with two or more lights in a circuit are usually caused by electrical circuit problems.
