OptoGlo Solar Signs Keep Your Messages Bright

Our technology is breakthrough and our signs are unique — they literally glow in the dark, without costing you a cent in electricity. But what makes OptoGlo a game-changer is its many benefits.

OptoGlo’s day and night visibility is unbeatable for driving customer traffic, promoting events, boosting visibility, gaining a competitive edge, enabling wayfinding, and improving safety messages.

We set out to invent the first solar sign with curb appeal. No clunky solar array on top or unwieldy lighting structures. No plugs or wires. Longer visibility for less solar exposure. And instead of just shining light onto a daytime sign, we invented a sign that gives a bright, even, long-lasting glow from within.

OptoGlo’s unique patent pending solar-powered illumination technology means our solar signs are completely self-contained. The sign itself holds both the solar cell and illumination components within it — along with the battery that lets it shine for up to 6 hours and the sensor that turns the sign on and off.


OptoGlo’s A-Frame solar signs look great, go anywhere, and require literally zero set-up and break-down.
