Neon lights glow in many colors. 


Neon lights are bright glass tubes. 


Neon lights are bright, glowing glass tubes. 

The color of the light depends on the gas used. Neon is a noble gas that gives off orange light. Other gases make different colors. Hydrogen makes purple-red light. Helium makes yellow or pink light. Mercury can make blue light. 
People use these tubes to make neon signs. These signs can be bent into letters or pictures. They were very popular for ads from the 1920s to the 1960s. In the US, many cities were bright with these signs. One famous place was Times Square in New York.
Neon lighting creates bright, glowing colors using glass tubes. 

The color of the glow depends on which gas is inside. Neon is a noble gas that creates a popular orange light. Other gases make different colors. Hydrogen produces a purple-red light. Helium makes a yellow or pink light. Carbon dioxide makes a white light. Mercury can create a blue light. 
Scientists first discovered neon in 1898. British scientists William Ramsay and Morris W. Travers found it in the atmosphere. They used an electrical gas-discharge tube to study it. Later, a French engineer named Georges Claude showed modern neon lighting in 1910. He presented it at the Paris Motor Show. Claude was sometimes called "the Edison of France." His company, Air Liquide, began making large amounts of neon after 1902. 
Neon signs became very famous in the United States. By 1940, almost every city downtown was bright with neon. Times Square in New York City became known for its huge neon displays. 
You might see neon used in many different ways today. Large signs like Vegas Vic show how artistic they can be.
Neon lighting is a type of cold cathode gas-discharge light. It produces bright, colorful glows using electrified glass tubes or bulbs. These lights are famous for creating dramatic signage used in advertising. They can also appear as tiny indicator lights in electronic devices. Today, artists and architects use neon to create large-scale installations.
The mechanism of a neon light relies on physics inside a sealed glass tube. Each tube contains a metal electrode at both ends. The tube is filled with a specific gas at low pressure. This low pressure is often between 3 and 20 Torr. When a high potential of several thousand volts is applied to the electrodes, it ionizes the gas. This ionization process causes the gas to emit visible light. 
The color of the light depends entirely on the gas used inside the tube. Neon is a noble gas that produces a popular orange-red light. Other gases create different colors, such as hydrogen for purple-red or helium for yellow or pink. Carbon dioxide produces white light, while mercury creates blue light. 
History shows that the discovery of neon led to a massive lighting industry. British scientists William Ramsay and Morris W. Travers discovered neon in 1898. They used an electrical gas-discharge tube to study its properties. Later, French engineer Georges Claude presented neon lighting in its modern form. He demonstrated bright red neon tubes at the Paris Motor Show in December 1910. Claude was often called "the Edison of France." 
Neon signage became a major cultural phenomenon in the United States. By 1940, nearly every city downtown was bright with neon signs. Times Square in New York City became world-famous for its neon extravagances. 
There is also a smaller version of this technology called the neon glow lamp. Daniel McFarlan Moore developed these miniature lamps in 1917. Unlike large tubes, these use a principle called coronal discharge. They consist of two electrodes placed very close together in a small bulb. These lamps can be less than one centimeter long. They were used for decades as small indicator lights in electronics and home appliances. 
Neon technology has connected to many different fields over time. The development of phosphors for color televisions in the 1950s created nearly 100 new colors for neon lighting. Furthermore, the technology used in small glow lamps helped lead to contemporary plasma displays and televisions.
