What’s the difference between a front-lit, halo-lit, and back-lit sign?

A front-lit sign projects light through the acrylic face for vibrant visibility.

A halo-lit sign (also known as a reverse-lit sign) emits light from behind the letters, creating a soft glow on the wall surface.

Back-lit or compound-lit signs combine both methods for a more dynamic effect, offering maximum visibility during both day and night.
