Wig-wag (automobile)
A wig-wag is a device for flashing an automobile's headlamps, in its simplest form so that only one of the two headlights operates at a time, with the two flashing at a preset rate. In its traditional form a wig-wag constitutes the illuminating of the right and left headlamps alternately, with each lamp lit for around half a second at a time. In the United Kingdom the wig-wag is only seen on the road on emergency vehicles. The 'standard' wig-wag is often used within a cycle of other illumination patterns, such as swiftly alternating the left and right headlights, alternating the left and right headlights slowly, or flashing both headlights together, and using a mixture of high- and low-/dipped-beams. Although the use of flashing headlights does increase the visibility of any vehicle, it can also create problems. In situations when highbeam headlights are flashed, the wig-wag may create glare or may otherwise temporarily blind the drivers of oncoming vehicles. Generally, wig-wa ...

Automobile
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headlamp
A headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage, ''headlamp'' is the term for the device itself and ''headlight'' is the term for the beam of light produced and distributed by the device. Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness. Other vehicles, such as trains and aircraft, are required to have headlamps. Bicycle headlamps are often used on bicycles, and are required in some jurisdictions. They can be powered by a battery or a small generator like a bottle or hub dynamo. History of automotive headlamps Origins The first horseless carriages used carriage lamp ...

Motorcycle Headlamp Modulator
A motorcycle headlamp modulator (or simply headlamp modulator) is an accessory device that oscillates the intensity of a motorcycle headlamp at 240 ±40 cycles per minute (~4 Hz) between approximately 20% and 100% of full intensity. The headlight operates at full intensity 50-70% of the time. United States and Canadian regulations require headlight modulators to include a light sensor that disables modulation when the ambient light level drops below a certain point. When this happens, the headlamps burn steadily. Purpose Motorcycles in the United States since 1978 have been wired so as to operate the low-beam headlamp whenever the engine is running. This is not required by any federal regulation but rather is a matter of voluntary industry policy. However, as increasing numbers of vehicles are equipped with daytime running lights, daytime-illuminated motorcycle headlamp may no longer provide a significant conspicuity benefit. Some motorcyclists install headlamp modulators in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Vehicle Equipment
Emergency vehicle equipment is any equipment fitted to, or carried by, an emergency vehicle, other than the equipment that a standard non-emergency vehicle is fitted with (such as headlights, steering wheels, and windshield/windscreens). Visual warning devices Emergency vehicles of any kind (fire truck, ambulance, police car) are highly likely to be involved in hazardous situations, including relatively common incidents such as a road traffic collision. They are also required to gain access to incidents as quickly as possible, and in many countries, are given dispensation from obeying certain traffic laws; for instance, they may be able to treat a red traffic light or stop sign as a ''give way'', or be permitted to break the speed limit. However, emergency vehicles usually are not able to treat a railroad crossing as a ''give way,'' because a train cannot be warned in time to stop before the crossing to let the vehicle through. Hence, one of the few things emergency vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
