Christmas Tree (drag Racing)
Modern drag races are started electronically by a system known as a Christmas tree. A common Christmas tree consists of a column of seven lights for each driver or lane, as well as a set of light beams across the track itself. Each side of the column of lights is the same; from the top down, there are a blue LED light set, then three amber bulbs, then a green bulb and a red bulb. The light beams are arranged with one set on the starting line, and another set 7 inches behind it. When drivers are preparing to race, they first cross the beams 7 inches behind the starting line. Crossing this beam activates the top bulbs. At this point, with most modern starting lights, the tree is activated. Once pre-staged, drivers roll up 7 inches and cross the second beam on the starting line, bottom bulbs, Once the first driver activates the bottom bulbs, the subsequent drivers have seven seconds or they are timed out and automatically disqualified, even in qualifying (a red-light foul is ignor ...

Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (UV) ...

Race America
''Alex DeMeo's Race America'' (also known in Europe as ''Corvette ZR-1 Challenge'') is a racing game, racing video game for the Nintendo Entertainment System. The European version received the Chevrolet license to use its Chevrolet_Corvette_(C4)#ZR-1_(1990–1995), Corvette ZR-1 vehicles while those in the North American version had to be redesigned into vehicles that strongly resembled Dodge Vipers. Gameplay The game involves at driving on roads in the United States, at approximately per hour from Boston to Los Angeles - from start to finish. In the 2-player mode, the players race against each other using the same car model, but in different colors. In the single player mode, each player must compete against eight computer-controlled cars across the U.S. The drivers are all fictional and are not based on any racers of the era.

International Hot Rod Association
The International Hot Rod Association (IHRA) is the second-largest drag racing sanctioning body after the National Hot Rod Association (NHRA). The Carrier Era 1971-1987 The IHRA was formed in November 1970 by businessman Larry Carrier. Throughout this period the organization was operated primarily in the south-eastern United States from its headquarters in Bristol, Tennessee. The IHRA initially followed the NHRA's professional class structure of Top Fuel, Funny Car and Pro Stock until the 1984 season when it decided to drop the premier Top Fuel category, an arrangement that only lasted three years before the class was reinstated for the 1987 season. Carrier is also credited with initiating drag racing's long-term sponsorship association with the R.J. Reynolds Tobacco Company's Winston (cigarette), Winston brand, which has ended. 1988-98 IHRA headquarters briefly moved to Waco, Texas in 1988 after it was purchased by Texan racer and track operator Billy Meyer who made many chan ...

Royal Purple Raceway
Houston Raceway Park, formerly known as Royal Purple Raceway, is a quarter-mile dragstrip in Baytown, Texas, just outside Houston. Built in 1988, the Park is situated on 500 acres on the eastern edge of the greater Houston metropolitan area and is Houston's only major multi-purpose motorsports venue. The dragstrip has a three-story tower building that incorporates 23 VIP suites, a media center, and race control facilities equipped with timing and scoring equipment. In 2000, Houston Raceway Park opened a new high banked 3/8 mile dirt oval at the facility. Houston Raceway Park's paved pit area holds approximately 400 racing rigs, with additional pit parking available on grass. The spectator parking lots have a capacity of over 10,000 cars, along with a special VIP parking area capable of holding an additional 600 vehicles. The Park has a seating capacity of 30,000, with additional grandstand seating brought in during major events to accommodate reserved seat requests. Houston Race ...

Top Fuel
Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of and finishing the runs in 3.62 seconds. A top fuel dragster accelerates from a standstill to in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach ) and can exceed in just . This subjects the driver to an average acceleration of about over the duration of the race and with a peak of over . Because of the speeds, this class exclusively races to only a distance, and not the traditional one-fourth of a statute mile, or . The rule was changed in 2008 by the National Hot Rod Association following the fatal crash of Funny Car driver Scott Kalitta during a qualifying session at Old Bridge Township Raceway Park in Englishtown, New Jersey. The shortening of the distance was used by the FIA at some tracks, and as of 2012 is n ...

Incandescent Light Bulb
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting, converting les ...

Lucas Oil Raceway
Lucas Oil Indianapolis Raceway Park (formerly Indianapolis Raceway Park, O'Reilly Raceway Park at Indianapolis, and Lucas Oil Raceway) is an auto racing facility in Brownsburg, Indiana, United States, about northwest of downtown Indianapolis. It includes a oval track, a road course (which has fallen into disrepair and is no longer used), and a drag strip which is among the premier drag racing venues in the world. The complex receives about 500,000 visitors annually. History In 1958, 15 Indianapolis-area businessmen and racing professionals led by Tom Binford, Frank Dickie, Rodger Ward, and Howard Fieber invested $5,000 each to fund the development of a farm tract into a recreational sporting complex that would focus on auto racing. The original intention was to create a 15-turn, road course, but as an insurance measure against economic problems, the investment group decided to incorporate a quarter-mile drag strip into the long straightaway of the road course design.

Drag Racing
Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly , with a shorter, distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s. The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing and as a regulated motorsport. History Drag racing started in the 1940s. World War II veterans were prominently involved, and some early drag races were done at decommissioned aircraft b ...
