Sign Customiser now fully supports slim lightbox designs inside the customiser. If your lightbox signs only illuminate from one side — like a wall-mounted sign that doesn’t need a lit back panel — the 3D preview now accurately reflects this by showing the border trim on any disabled sides. You can also enable recessed borders for a cleaner, more modern look where the border sits flush with the face rather than overlapping it.

What’s Changed
- Slim (single-sided) lightbox support - Lightbox signs with inactive sides are now officially supported in the customiser. Disabled sides display the border colour instead of a lit panel, giving customers an accurate preview of how the finished sign will look
- Recessed border option - A new setting allows merchants to enable recessed borders on lightbox signs, removing the visible trim overlay from the face and back panels for a sleek, frameless appearance
- Accurate 3D preview - The lightbox renderer correctly hides glow effects and images on inactive sides, so the preview matches the real product — whether it’s a single-sided wall sign or a fully illuminated hanging lightbox
- Works across all lightbox shapes - Box, circle, and oval lightbox shapes all support inactive sides and recessed borders
- Automatic border trim enforcement - The admin and customiser now ensure lightbox signs always have the required border trim colour assigned, preventing incomplete configurations from reaching your customers
