Headlight
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 lamps ...

Fog Lamp
Automotive lighting is functional exterior lighting in vehicles. A motor vehicle has lighting and signaling devices mounted to or integrated into its front, rear, sides, and, in some cases, top. Various devices have the dual function of illuminating the road ahead for the driver, and making the vehicle visible to others, with indications to them of turning, slowing or stopping, etc., with lights also indicating the size of some large vehicles. Many emergency vehicles have distinctive lighting equipment to warn drivers of their presence. History Early road vehicles used fuelled lamps before the availability of electric lighting. The first Ford Model T used carbide lamps for headlights and oil lamps for tail lights. It did not have all-electric lighting as a standard feature until several years after its introduction. Dynamos for automobile headlights were first fitted around 1908 and became commonplace in 1920s automobiles. Trafficators—signalling arms that flipped up ...

Citroën DS
The Citroën DS () is a Front-mid-engine, front-wheel-drive layout, front mid-engined, front-wheel drive executive car manufactured and marketed by Citroën from 1955 to 1975, in fastback/sedan, wagon/estate, and convertible body configurations, across three series of one generation. Marketed with a less expensive variant, the Citroën ID, the DS was known for its aerodynamic, futuristic body design; unorthodox, quirky, and innovative technology, and set new standards in ride quality, car handling, handling, and braking, thanks to both being the first mass production car equipped with hydropneumatic suspension, as well as disc brakes. The 1967 series 3 also introduced ''directional headlights'' to a mass-produced car.After this feature was first introduced on the 1948 Tucker 'Torpedo', of which 50 were built. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car, and Paul Magès developed th ...

Bicycle Lighting
Bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination. A secondary purpose is to illuminate reflective materials such as cat's eyes and traffic signs. A third purpose may be to illuminate the roadway so that the rider can see the way ahead. Serving the latter purposes require much more luminous flux and thus more power. Many jurisdictions require one or more bicycle lights to be fitted to bicycles ridden at night — generally a white light in the front and a red light at the back, like with other vehicles. History Fire The earliest bicycle lamps were oil-fueled and started to be manufactured in 1876 for the Ordinary (High-Bicycle) and solid-tired tricycles. From 1896, acetylene gas lighting for bicycles started to be introduced and later in 1899, acetylene gas lamps for the motor-car became popula ...

Ford F-Series
The Ford F-Series is a series of light-duty trucks marketed and manufactured by Ford Motor Company since model year 1948 as a range of full-sized pickup trucks — positioned between Ford's Ford Ranger (T6), Ranger and Ford Super Duty, Super Duty pickup trucks. Alongside the F-150 (introduced in 1975), the F-Series also includes the Super Duty series (introduced in 1999), which includes the heavier-duty F-250 through F-450 pickups, F-450/F-550 chassis cabs, and F-600/F-650/F-750 Class 6–8 commercial trucks. History The F-Series was introduced in 1948 as a replacement for a previous pickup model line based on car platforms. The most popular version of the model line is the F-150 pickup truck, currently in its fourteenth generation (introduced for the 2021 model year). From 1953 to 1983, the entry-level F-Series pickup was the ton F-100. Starting in 1984, the F-150 became the entry-level. The F-150 has a long-running high-performance off-road trim level introduced fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Halogen Lamp
A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine. The combination of the halogen gas and the tungsten filament produces a halogen-cycle chemical reaction, which redeposits evaporated tungsten on the filament, increasing its life and maintaining the clarity of the envelope. This allows the filament to operate at a higher temperature than a standard incandescent lamp of similar power and operating life; this also produces light with higher luminous efficacy and color temperature. The small size of halogen lamps permits their use in compact optical systems for projectors and illumination. The small glass envelope may be enclosed in a much larger outer glass bulb, which has a lower temperature, protects the inner bulb from contamination, and ...

Cadillac (automobile)
Cadillac Motor Car Division, or simply Cadillac (), is the luxury vehicle division of the American automobile manufacturer General Motors (GM). Its major markets are the United States, Canada and China; Cadillac models are distributed in 34 additional markets worldwide. Historically, Cadillac automobiles were at the top of the luxury field within the United States, but have been outsold by European luxury brands including BMW and Mercedes since the 2000s.

Tatra T77
The Tatra 77 (T77) is one of the first serial-produced, truly aerodynamically-designed automobiles, produced by Czechoslovak company Tatra from 1934 to 1938. It was developed by Hans Ledwinka and Paul Jaray, the Zeppelin aerodynamic engineer. Launched in 1934, the Tatra 77 is a coach-built automobile, constructed on a platform chassis with a pressed box-section steel backbone rather than Tatra's trademark tubular chassis, and is powered by a rear-mounted 2.97-litre air-cooled V8 engine, in later series increased to a 3.4-litre engine. It possessed advanced engineering features, such as overhead valves, hemispherical combustion chambers, a dry sump, fully independent suspension, rear swing axles and extensive use of lightweight magnesium alloy for the engine, transmission, suspension and body. The average drag coefficient of a 1:5 model of Tatra 77 was recorded as 0.2455. The later model T77a, introduced in 1935, has a top speed of over due to its advanced aerodynamic design ...

Carbide Lamp
A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C2H2), which is created by the reaction of calcium carbide (CaC2) with water (H2O). Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century. They are still employed by Caving, cavers, hunters, and cataphiles. History In 1892, Thomas Willson discovered an economically efficient process for creating calcium carbide in an electric arc furnace from a mixture of Lime (material), lime and Coke (fuel), coke. The arc furnace provides the high temperature required to drive the reaction. Manufacture of calcium carbide was an important part of the industrial revolution in chemistry, and was made possible in the United States as a result of massive amounts of inexpensive hydroelectric power produced at Niagara Fal ...
