Neon signs are illuminated signs that display writings and symbols in different colors. Classic neon signs are made using glass tubes filled with inert gases such as neon and hence the name ‘neon signs’.

Who Invented Neon Signs?

Neon signs were invented by Frenchman Georges Claude in 1910. However, while his work was the final breakthrough, the concept of neon lighting dates as far back as the 1800s. The following are some major milestones in the invention of neon signs.

1675: The discovery of the barometric light – the French astronomer, Jean Picard, noticed that whenever mercury in a glass was shaken, it discharged some light. This phenomenon was christened barometric light. It relates to neon signs on the principle that when certain atoms are activated in a vacuum, they can light up.

1855: The invention of the Geissler tube – Heinrich Geissler was a physicist and a glassblower. He invented the Geissler tube which is a partially evacuated glass cylinder with an electrode on each end. His knowledge of molding glass also enabled him to craft different shapes. A Geissler tube filled with inert gas and connected to an electric current would have worked as a neon light. The problem was that the glass tubes were only partially evacuated.

1902: The invention of the Claude System – the Claude system was invented by George Claude. It is a method of liquefying air that made it possible to mass-produce purer forms of inert gases.

1910: The invention of neon lighting – using the Claude system and improved vacuum systems, George Claude created the first successful neon light. His first display consisted of 40-foot neon tubes.

Types of Neon Signs

Neon signs differ based on how they are made. There are 2 main types:

Traditional Neon Signs

Traditional neon signs are based on George Claude’s model. They are made of glass tubes, with an electrode on each end and filled with inert gases. The glass tubes are designed in different shapes depending on the message that is to be displayed on the sign. Different inert gases can also be used to achieve a multicolored sign.

These types of signs work as follows:

LED Neon Light Signs

LED neon light signs look just like traditional neon signs. An untrained eye may not even be able to tell the difference. However, the two are not built the same. Instead of gas-filled glass tubes, LED neon light signs are made using flexible LED neon light strips.

The flexibility of the LED neon light strips allows for them to be bent into different letters or shapes to make a sign. Once the sign is complete, the power source of the LED neon lights is turned on and the sign lights up. RGB LED neon lights or RGBW neon lights can be used to display different colors just like in traditional neon signs.

How Long Do Neon Signs Last?

The durability of your neon sign depends on the type of neon sign you choose. The longevity of a traditional neon light sign can be divided into two aspects; the durability of the transformer and the glass tube.

The transformer – serves as the power source of the neon sign. It has a typical lifespan of about 8 to 10 years. This depends on how long the sign stays on in a day and where the sign is placed. Low usage, as well as indoor or sheltered placement, may contribute to the sign lasting longer.

The glass tube –neon sign glass tubes can last 8 to 10 years as well but they are more prone to damage. Extreme temperatures, hailstones, or heavy snowballs could break the glass. On the upside, you could repair the broken tube but it may cost you a pretty penny.

Good quality LED neon flex lights can have a lifespan of over 50,000 hours. They are often jacketed in silicone which makes them resistant to water damage, impact, and different kinds of corrosion. For these reasons, they make neon signs that are very durable and can last as long as 20 years. Further, due to their resilient design, the longevity of LED neon light signs is not significantly affected by outdoor or indoor settings.

Some tips to ensure that your neon sign lasts longer include:

Applications of Neon Signs

When you need to display a message to large or small audiences, you simply cannot go wrong with neon signs. They are applicable for:


Neon Sign

Traditional neon signs made their debut in advertising in 1923. A car company bought them from George Claude and used them to advertise their business. The competition soon joined in the fray and since then neon lights became a staple medium of advertising.

Neon signs meet all the markers of a good advertising tool. They attract attention and can communicate a message clearly. They are also an affordable medium given as a neon sign is a one-time investment that will serve you in perpetuity.


LED neon signs are more commonly used for this type of application. This is because they are easier to make and can be designed in different sizes. Plus, they work well for both indoor and outdoor installations.

For home decor, a neon sign can be used to accentuate a feature wall or as a cool way to minimally illuminate a space. While at events such as weddings and parties, neon signs are now a common preference for a photo area backdrop. It is also possible to use them on building facades or parks during the holidays as festive decorations displaying season’s greetings.

How Are Traditional Neon Signs Made?

Almost all traditional neon signs are custom made. The manufacturing process thus begins with designing the sign and determining its size. This is a very important step as once the glass tubes have been molded they can not be adjusted. The manufacturing process then proceeds as below.

The Glass Tubes

Glass tubes in a kiln

Neon signs are made using soft lead glass tubing. The glass tubing undergoes a series of steps to create the sign as needed.

The heat is usually applied where the glass tubing needs to be bent but it is conducted to the rest of the tube to prevent the whole glass tube from collapsing as it softens, air is blown into it through one of its openings. When the process is completed, the electrodes are inserted.

The Electrodes


Each unique section of glass tubing has 2 electrodes. In the letter ‘A’ for instance, there would be an electrode at the end of each tail.

The electrodes used are made of pure iron and are usually encased in glass. The glass jacket is enclosed on one end and left open on the other. The open end faces the inside of the glass tubing while the other faces outside.

Each electrode has a wire that juts out at the closed end. Whereas every letter or shape is individual, they need to form a complete circuit for the whole sign to light up. To this end, each electrode is joined to the next using a GTO cable. The GTO cable then joins all of them to the transformer. The point of connection between the cable and the transformer is jacketed in heat-resistant borosilicate glass.

Inert Gas

When the electrodes are in place, the glass tubing is bombarded to remove all impurities. After it cools, the inert gas is inserted through a small portal which is then sealed off. The purer the gas, the more durable and well-illuminated the sign will be.

The type of inert gas used depends on the color that needs to be displayed. They include:

The Aging Process

In this step, the glass tube filled with gas is heated to a set temperature. The purpose of this process is to anneal the glass and also help the inert gas settle into the tube evenly.

After the aged tube cools, the electrodes are connected to a transformer for testing. For it to pass the test, it has to illuminate evenly, with no sparks or dimming.

When every glass tube in a sign passes the quality test, they are joined into a circuit mounted onto a board. The sign is connected to a transformer which steps up the normal voltage of 120-220V to up to 15,000 volts to power the neon sign. In terms of current, a neon sign requires about 30-60 milliamperes.

For outdoor installations, the transformer should always be in a waterproof cabinet to protect it from rain, snow, and other elements.

How Are LED Neon Light Signs Made?

LED neon light signs are much easier to make. So much so that you can make them at home. They are made up of 3 main parts:

The production process begins with an illustration of the sign. It is then printed to scale to be used as a template.

Choosing LED Neon Flex Lights

The quality of the sign is largely determined by the quality of LED neon flex lights that are used to make it. Quality brands offer features such as:

High-grade silicone encasing

Bright even lighting throughout the light strip

Radiant consistent color


Energy efficiency

The choice of LED neon flex lights is also determined by color. Most reputable LED neon flex manufacturers offer RGB and RGBW neon flex lights; they provide more color options increasingly in that order.

Preparing the Backboard/Substrate

LED neon light signs are made by mounting LED neon flex lights onto surfaces referred to as backboards of substrates. PVC and acrylic plastic are the most common choices for most manufacturers. They are durable and transparent enough for the light to beam through them properly.

The template serves as a guide when preparing the substrate. First, the length and width of the sketch are measured. The substrate is then cut to a size big enough to accommodate both measurements. Some backboards come pre-cut which may be useful if you choose to make your LED neon lights sign at home.

Some manufacturers carve letters or shapes into the substrate while others sketch them on the surface. Either method is acceptable. The only difference is that a carved substrate enables better accuracy as the LED neon flex lights are inserted into the carved spaces. Carving may also make it easier for them to stay in place as opposed to a surface placement.

Finally, holes are drilled at the end of each point of each letter. For example, in the word ‘IS’ there should be a hole at the bottom between ‘I’ and ‘S’ as well as between ‘S’ and the next letter.

Putting Together the Sign

When the substrate is ready, the LED neon light sign is assembled as follows.

Wiring the Sign

Each section of LED neon flex lights needs to be connected to the next one to create a complete circuit.

If the circuit is well connected, the sign should light up with no noise or sparks. The lighting should also be even with no dark spots on letters or shapes. If certain sections are dim, then the sign might be too large for one power supply which may warrant an amplifier.

Installing an indoor sign is a straightforward process. It can be screwed on or suspended on hooks that can bear the weight. All installation should be done cautiously so as not to interfere with wiring or the LED neon flex lights.

Outdoor installations require the LED neon light sign to be wrapped in a transparent waterproof jacket. An acrylic box, for instance, would be ideal for this.

How Much Do Neon Signs Cost?

Neon signs can cost as low as $200 to thousands of dollars. This price range is due to multiple factors:

The intricate work that goes into making neon glass signs raises their cost of production and in turn, their price. Aside from the initial cost, maintenance can equally be quite costly. Repairing a broken glass tube, for instance, requires a fresh tube to be created from scratch. Some shops also bill more for such services as some glass tubes contain mercury which presents a health risk.

In contrast, LED neon light signs are made using affordable components such as LED neon lights and the production process is easy. Additionally, they require little maintenance as both the lights and substrates are built using durable material. However, custom LED neon light signs are more expensive than generic ready-made designs. You could, nonetheless, get around this by making your own.

Where to Buy Neon Signs

Traditional neon signs are quite fragile both structurally and in terms of safety. Making the glass tubes is an art that not just anyone can pull off. They have to be just the right size and length and filled with the right amount of inert gas or else the sign will not light up. In light of this, it is imperative that you purchase your neon sign from a certified professional neon sign maker.

On the other hand, with LED neon light signs you can choose to buy or make your own. DIY LED neon signs are an advantageous option as they are much cheaper. Buying LED neon flex lights wholesale, for example, attracts lower prices and allows you to make as many signs as you like. That said, large commercial signs may require a more skilled hand as they may be a bit more complex to make and install.

In either scenario, you can find a signmaker or buy a ready-made sign through:

Ecommerce Platforms

Online searches are ideal for situations where you need to commission a custom neon sign. Nevertheless, the success of your search will depend on the accuracy of your description and some discernment.

Be advised that not all neon signmakers offer customization services. Additionally, there are traditional/classic neon signmakers and LED neon light signmakers. Your search terms should thus be guided by these distinctions.

When you have a list of options, compare prices against the value that each signmaker offers. Considers factors such as:

Materials used – acrylic substrate LED neon light signs, for example, may be a smidge more expensive than PVC.

The number of customization options being offered – they should include a choice of font type, size of the letters, colors for the sign, and Indoor or outdoor design provisions

Provision of an installation kit

Installation services especially for a traditional neon sign

Local Inquiries
