Reverse-Lit Channel Letters (also commonly referred to as halo or back-lit letters) are distinctive signs that showcase a high-end prestigious look. These types of letters are complete fabricated aluminum letters with bright LED modules housed inside the letter. Letters are installed stand-off
from the surface (or on raceway). During the day, all definitive colors and styles are shown, and at night the letters turn dark and a “halo” or “glow” effect appears around the letter.
