Zusammenfassung:	This disclosure provides systems, methods and apparatus for a front illumination device with metalized light-turning features. In one aspect, an illumination device includes a light guide having light-turning features that include recesses formed on the light guide and that extend down into the light guide. The recesses may be coated with a material where the material also forms an auxiliary structure outside of the recesses on the light guide. The auxiliary structure may be conductive and may form, for example, an electrode. L'invention porte sur des systèmes, sur des procédés et sur un appareil pour un dispositif d'éclairage avant comportant des éléments de rotation de lumière métallisés. Dans un aspect, un dispositif d'éclairage comprend un guide de lumière ayant des éléments de rotation de lumière qui comprennent des cavités formées sur le guide de lumière et qui s'étendent vers le bas dans le guide de lumière. Les cavités peuvent être revêtues par un matériau, le matériau formant également une structure auxiliaire à l'extérieur des cavités sur le guide de lumière. La structure auxiliaire peut être conductrice, et peut former, par exemple, une électrode.
