Which Custom Neon Signs Offer the Best Warranty?
Ethan Carter
In modern home decoration, corporate branding, and high-end events, the role of custom signs has long gone beyond just lighting. It has become a key factor in visual marketing and an expression of brand image.
However, if the signs are used for a long time or in an incorrect manner, they are prone to issues like fading over time. So, it’s key to pick a manufacturer that provides strong after-sales support when buying a custom neon sign.
I. What are common neon sign repair issues?
Whether it is traditional glass signs or modern LED neon signs, the most common failure problems fall into the following three types.
● Won't Turn On
The main issue is that the transformer burns out from too much use, or the controller fails. This leads to a complete power outage.
● Partial Section Failure
This situation occurs when some of the parts malfunction. In LED neon signs, this is caused by disconnected circuits or loose contact points. In traditional glass signs, the reasons for this situation often lie in the breakage of the glass tubes or the leakage of the gas.
● Flickering or Uneven Brightness
Uneven flashing in neon signs often happens because of unstable voltage or faulty dimmers. It can also be caused by signal interference and quick damage to LED chips from overheating.
Our factory stress tests show that 85% of early LED neon failures come from unventilated power supply drivers, not from sign strip defects.
II. How does neon sign repair work?
Before repairing, it is necessary to conduct a problem diagnosis to determine which part has malfunctioned. The maintenance personnel will first disconnect all power sources to prevent the risk of electric shock. They will use a multimeter to measure the voltage output of the power supply, the dimmer, and each section to identify the faulty point.
The maintenance methods and difficulties for LED neon signs and traditional glass neon signs are also different.
LED neon sign repair
The maintenance of LED neon signs is relatively simple. Technicians can remove the damaged part of the silicone casing, replace the damaged light strips, and then re-seal the area with waterproof silicone. Thus, the damaged components can be repaired without replacing the entire neon light. This not only improves efficiency but also reduces the waiting time for customers.
Traditional glass neon sign repair
Repairing traditional glass neon signs is more complicated because broken glass tubes usually cannot be directly repaired. Technicians need to bend a new glass tube that matches the original shape and design. After the tube is replaced and shaped, technicians must remove the air and impurities inside the tube so that it can work properly. Compared with LED neon signs, maintaining glass neon signs requires more professional skills, takes longer, and incurs higher labor costs.
When should a neon sign be repaired vs replaced?
Whether to repair or replace the neon lights mainly depends on cost-effectiveness. If the problem lies outside, such as a controller failure or minor contact issues, the best course of action is to have it repaired. However, if the repair cost is close to half of the original price of the item, or if the neon lights are severely damaged, it is best to replace them with a new one.
How long does neon sign repair usually take?
Repairing LED neon lights usually takes 1 to 3 working days. The repair time will vary depending on the damaged components and the difficulty of the repair.
III. How to Create a DIY Sign Design?
Although it's very convenient to buy neon signs online, it's also quite simple to make them yourself. If you prefer to do it yourself, follow these four simple steps, and you will be able to create a beautiful DIY neon sign.
● Step 1: Create a design sketch
First, outline your ideas and draw them on the computer.
● Step 2: Prepare an acrylic backing sheet
After completing the design, prepare a transparent acrylic backplate. Securely stick the design drawing onto the backplate so that the lines can be clearly seen from the front.
● Step 3: Mark the perforation positions
Mark the positions on the back panel where the wires need to pass through.
● Step 4: Shape the Neon Tubes and Connect Wires
Follow the design drawing to make the neon signs, and then connect the wires of each section using quick connectors. In this way, a DIY neon light was completed.
Of course, you can also use the AI design tools provided by the GS-JJ website to complete your creation. Just describe your ideas, and our AI designers can produce the initial design draft within a few seconds.
What sizes and fonts work best for custom neon signs?
When choosing the font, avoid using fonts with overly thin strokes or overly complex designs. The thickness of the font should be at least 8-10 millimeters. Each letter should be at least 10-15 centimeters tall. If they are too small, it can strain the internal circuits and cause disconnection.
What should you check before installing a neon sign?
The most crucial step before installing neon signs on the wall is to ensure the wall can bear their weight. To prevent overheating, it is also necessary to ensure that the power it operates at does not exceed 80% of its rated power. For outdoor-installed neon signs, make sure that the power supply is placed in a waterproof box with an IP67 protection rating.

What Warranty Coverage Should You Expect From Custom Neon Signs?
The warranty coverage for neon signs typically includes LED light strips, power supplies, controllers, and key components such as manufacturing defects.
The warranty period varies depending on the manufacturer and the installation environment. For instance, indoor neon signs usually have a longer warranty period than outdoor signs because outdoor exposure accelerates material aging.
How Long Do Neon Signs Last and How Do You Maintain Them?
The lifespan of most high-quality neons is typically between 30,000 and 50,000 hours. The actual service life mainly depends on the following factors.
● Chip quality: High-quality LED chips can greatly lower light attenuation.
● Operation time: Cooling the neon signs when not in use can extend their lifespan.
● Installation environment: Keeping the silicone diffuser in a damp, sunny, or dusty place will speed up its aging.

● Prevent moisture: Place the power adapter and dimmer switch in a dry and ventilated area, and regularly check for wear on the silicone gasket.
V. How does neon manufacturing work?
To create a high-quality custom neon sign system, the manufacturer must follow these steps.
Design Preparation: First, we convert the design drawings into precise templates. Then, a laser cuts the back panel to fit the design outline.
Embedded light strips: High color-rendering LED strips are set in special silicone. This design gives smooth, spot-free lighting.
Welding and Waterproofing: You can make circuit connections by manual or automated soldering. Lead-free solder is used. Then, the circuit is covered with silicone rubber. This meets IP65 or IP67 standards for moisture protection.
Quality Inspection: Before shipping, products must complete a 24-48 hour aging test. This helps reduce early failure rates.

How to Choose the Ideal Neon Sign Size?
A neon sign is described as "a bright sign composed of either flexible LED neon or traditional glass neon tubes that gives off a bright glow." Most neon signs used to consist of glass tubes filled with neon gas, but now most neon signs will have LED equivalents that are more energy efficient, safer, lighter, and less brittle.
