Sign Guru is the first company to create a lighted portable sign that is back lit from the inside of the sign. Our illuminated portable sign is the best of all worlds as it incorporates a high quality digitally printed image with internal lights that allows the image to light up at night. This allows for extended hours of advertising for our clients. The goal is to help our clients attract more customers and a sign that lights up at night can be seen by passersby over a sign that simply fades into the darkness as the sun sets.
