A lightbox sign is a shallow enclosed box with a translucent face and LED lighting inside, so the whole panel, or just lettering routed into it, glows evenly at night.
Reasons to choose lightbox signs in Treharris
- Businesses with several sites across Mid Glamorgan can share one set of artwork, so the Treharris branch matches the rest.
- On a dimly lit Treharris side street, a lightbox brings its own light and helps customers find the door.
- A Treharris takeaway trading mostly after dark keeps its name and number readable with a fully lit face.

Consent for illuminated signs in Treharris
Wales has its own advertisement regulations, and a lit sign is the case where they matter most. Internally illuminated, halo-lit and lit projecting signs typically need express consent, and on listed buildings or in conservation areas the council is likely to look closely at size, light levels and fixings. Keep illumination static and moderate; PLG05 from the Institution of Lighting Professionals is the usual reference. LED modules and drivers run at low voltage, but the mains connection still needs an electrician working to BS 7671. We check before you commit and can prepare or submit the consent application.
