Channel letter signs are among the most popular and effective forms of business signage.
These three-dimensional letters are often found on storefronts, office buildings, shopping malls, and buildings facing highways. They help businesses look more professional and stand out. If you’ve ever passed a business at night and noticed glowing letters spelling its name, you’ve seen channel letter signs. This guide explains what they are, how they work, their benefits, and what to consider before getting one.
What Are Channel Letter Signs?

Channel letter signs are custom-made, three-dimensional letters and logos that businesses often illuminate. In addition, manufacturers build each letter on its own structure, giving it a premium three-dimensional appearance. As a result, retail stores, restaurants, offices, and shopping centers use these signs to enhance visibility and create a professional look during both the day and night. Furthermore, businesses can customize these signs to match their branding, making them an effective and long-lasting signage solution.
How Channel Letter Signs Work
Manufacturers build each letter using a metal or plastic frame called the “return.” They create the front of each letter from materials such as acrylic or metal. They install LED lights inside or behind the letters to produce bright, even illumination. The placement of these lights determines the overall appearance of the sign.
Types of Channel Letter Signs
Front-lit Channel Letters
Lights shine through the front of the letters, making them glow bright and even. This is the most common and least expensive type.
Back-lit (Halo-lit) Channel Letters
Lights shine from the back, creating a soft glow around the letters, like a halo.
Front-and-Back-lit Channel Letters
This type uses both front and back lighting for the brightest effect.
Open-face Channel Letters
These have an open front, showing the LED lights inside for a bold, neon-like look.
Non-illuminated Channel Letters
These are not lit up, used mainly during the day and are often chosen for their clean look without the need for electricity.
Push Through Signs

Push-through signs, also called push-through letter signs are a premium type of channel letter sign. They feature acrylic letters that extend through a metal or aluminum face, creating a bold three-dimensional appearance with clean, even LED illumination. These signs offer exceptional durability, weather resistance, and a modern look, making them ideal for retail stores, corporate offices, shopping centers, hotels, and luxury brands. Push-through signs provide excellent visibility during both the day and night while enhancing your business’s professional image.
