Designing Your Neon Flex Sign

Conceptualizing Your Design:

The design phase is crucial. Whether it's a catchy phrase, a brand logo, or an abstract shape, your design sets the tone for the entire project. Consider factors like visibility, aesthetics, and the message you want to convey.

Choosing the Right Neon Flex Tubing:

Neon flex tubing comes in various colors, thicknesses, and flexibilities. Select tubing that aligns with your design's complexity and aesthetic needs. The tubing's luminosity and color temperature are also important considerations.

Preparing for Construction

Selecting and Preparing the Backing Material:

The backing material, typically an acrylic sheet, provides structural support. Choose a thickness that can withstand the weight and manipulation of the tubing. Prepare the surface by cleaning it thoroughly and sanding any rough edges.

Transferring the Design:

If using a template, transfer your design onto the backing material. This can be done using a marker or by etching lightly onto the surface. Accuracy here is key to ensuring your tubing aligns perfectly with the design.

Constructing Your Neon Flex Sign

Measuring and Cutting the Tubing:

Measure the tubing against your design, allowing a little extra for adjustments. Cut the tubing with precision, ensuring clean edges for better connectivity and aesthetics.

Shaping the Tubing:

Carefully bend the tubing to match your design. This step requires patience and a gentle touch to avoid damaging the tubing. For complex designs, consider using a heat gun to slightly warm the tubing, making it more pliable.

Securing the Tubing:

Apply adhesive to the tubing and place it onto the backing material, following your design. Ensure each section is firmly pressed down and allow ample time for the adhesive to set.

Wiring and Power Setup:

Connect the ends of the neon flex tubing to the power supply. This step may involve soldering or using specific connectors, depending on the type of neon flex tubing you have chosen. Ensure all connections are insulated and secure.

Finishing Touches and Installation

Testing the Sign:

Once assembled, test the sign to ensure all sections light up and there are no electrical issues. Address any dim sections or connectivity problems.

Mounting the Sign:

Decide on the location for your sign. Consider factors like visibility, power source proximity, and the overall aesthetic of the space. Use the appropriate mounting hardware to secure the sign in place.

Maintenance and Care

Regularly clean the sign to maintain its brightness.

Inspect the electrical components periodically for signs of wear or damage.

If any section of the sign stops working, troubleshoot the connections and wiring.


Creating a neon flex sign is a fulfilling project that combines creativity, technical skill, and a bit of patience. The end result is a personalized, glowing piece of art that can transform any space. Whether for home decor, a special event, or business branding, a custom neon flex sign is a statement piece that's sure to draw attention.
