The lamp appears crystal clear when unlit but has a glowing appearance when lit. The light scattering properties of the new material convert the light guide to a fully illuminated panel, that can be used with any color LED, opening a new degree of freedom for designers. Previously, clear PMMA without this light
scattering additive was used, and structures on the surface of the light pipe, along with multiple LEDs behind the part, had to be used. These traditional light guides and light pipes resulted in bright spots and a milky (grained)unlit appearance. The new headlamps give the consumer premium headlamp styling due to a homogeneously lit light function. Safety is enhanced as there is better visibility due to a larger illuminated surface easier to detect with the human eye. A 3D effect can also be achieved.
