Why Upgrade to 4D Laser Cut Number Plates? (3mm vs 5mm Guide)

Upgrade your vehicle’s aesthetic with our premium 4D Laser Cut number plates, designed to replace dull, flat printed plates with something truly standout. Unlike standard options, these plates feature solid, high-gloss acrylic characters that sit proud of the reflective surface, delivering razor-sharp definition and a modern finish. But that is not all. Every license plate, despite its custom look, is still made to meet the BS AU 145e standard so that they will stay 100% legal for road use and will continue to pass the MOT, if ordered in the normal format.

If riders want to smooth their ride significantly, the 3mm 4D would be the right choice: it manages to stay pretty subtle while adding some style. Four millimetres is a pretty thin character depth, so the result is a very classy "OEM+" look that is just like a very expensive factory upgrade. If you want your license to exude freshness, neatness, and luxury without the aggressive or "loud" look on the bumper, then this is the right option.

Alternatively, if you want to make a bold statement, the 5mm 4D option delivers maximum visual impact. The thicker 5mm block creates deeper shadows and sharper angles, giving the text a much more distinct presence. This aggressive profile is particularly well-suited for modified cars, large SUVs, or anyone looking for a standout feature that truly pops and separates their vehicle from the rest of the traffic.

Standard Printed Hex

A clean, flush finish. Perfect for those who want the angular "Lambo" shape but prefer a smooth, traditional surface.

3D Gel Hex

Combine the custom shape with our 3D Gel Resin characters. The raised, glossy profile of the letters complements the sharp edges of the plate, giving your vehicle a premium, high-end look.

4D Laser Hex

The ultimate upgrade. We mount precision-cut 4D Acrylic digits onto the Hex plate. The sharp edges of the 4D block text match perfectly with the angular corners of the plate for a fully aggressive, modern aesthetic.
