Luckily, these location situations are where pylon signs truly shine. Pylon signs are free standing structures, usually reserved for exterior use, that are perfect for grabbing the attention of passing traffic due to their significant height and solid appearance. For an added visual punch, pylon signs can incorporate lighting, interesting shapes, and LED message displays. They can also accommodate information for multiple businesses at once.
