Storefront signs can be lit or non-lit. There are also different options for lighting. You could use non-lit flat-cut aluminum for your storefront sign, or you could utilize a lit raceway-mounted channel letter.
This sign incorporates a day-night vinyl where it appears black during the day, but appears white at night when the LEDs shine through the face!
Here is what this same sign looks like when lit at night! This gives the maximum visibility on white/light colored buildings.
This is a great example of a face-lit channel letter with day-night vinyl on the house structure, and white strokes around the green translucent to help it pop!
When lit, this channel letter shines through the backs of the letters onto a backdrop, giving it a glow effect!
