The 6mm 4D Shadow X Number Plate is a premium, road-legal registration plate created for drivers who want a bold, modern appearance without compromising UK compliance. Precision laser-cut 6mm raised acrylic characters feature a distinctive shadow-layer construction, combining a matte black top layer with a gloss black base to produce a sharp, stepped 3D shadow effect that enhances contemporary vehicle styling.
4D Shadow X number plates use raised 6mm acrylic characters layered over a contrasting base to produce a multi-dimensional shadow appearance. This design gives depth and definition while maintaining clean character edges that remain fully readable and compliant with UK regulations.
Unlike standard 4D plates, the Shadow X style introduces a visible separation between layers, creating a darker outline or “shadow” beneath each character. The matte-over-gloss finish enhances contrast and gives the plate a stealth, performance-inspired aesthetic.
These plates are made from top-notch acrylic material and use industrial-grade bonding for their construction. Thanks to their robust nature, they will not easily fade and also resist weather conditions and can be washed several times with a car wash without any trouble, hence they are perfect for vehicles being driven daily.
A dual-layer construction (3mm Gloss Base + 3mm Matte Top) creating a physical 'step' that adds unparalleled dimension.
The gloss backing reflects light while the matte face absorbs it, creating a natural 3D shadow effect visible from every angle.
Rigorously tested for reflectivity, spacing, and durability. Pass your MOT with zero stress.
Designed to enhance the appearance of contemporary vehicles.
Features 6mm hybrid construction (Acrylic + Gel). Ultra-gloss wet look, UV stable, impact resistant & fully BS AU 145e road legal compliant.

Yes. 4D Shadow X plates are road legal in the UK when manufactured to DVLA and BS AU 145e standards. This includes using solid black, non-removable characters in the correct Charles Wright font, with compliant spacing and reflective backgrounds.
4D Shadow X plates are ideal for drivers who want a stronger visual presence than standard 4D plates but prefer a cleaner, more refined look than aggressive hex styles. The layered shadow effect delivers depth without compromising readability or legality.
If you’re looking for a different finish, explore our 4D Gel Number Plates for a high-gloss wet look, or our Hex Number Plates for a more aggressive performance style.
