Our Mission: “To Simplify the Lives of Our Customers”

We Speak Sign Language

Our team has over 150 years of combined experience serving the LED signage market and we treat our customers as part of our family. Principal LED was founded on three basic pillars that are the foundation of everything we do. Our corporate headquarters and distribution facility is located in San Angelo, TX.


We strive to make the lives of our customers easier by simplifying the sign lighting process and providing the tools necessary to plan and implement a sign fabrication or retrofitting project. We are always looking for ways to create or innovate our products to save time and valuable resources. Our product development process starts from the needs of a sign builder or designer – not the other way around.

We believe people come first. That means dealing fairly with our customers, go-to-market partners, suppliers, and employees. Our primary goal is to create lasting relationships by providing superior service and value.


Our products are best in class in the signage market. Our company has a strong technical base in optoelectronics, material science, and process automation. We also understand what sign makers need, and how to translate these core skills into products that are both practical and innovative.


Our goal is to be the leader in value LED products without compromising performance and customer service. We achieve this through a corporate culture that emphasizes frugality and low overhead. We put our product dollars into driving performance and quality.
