The module has a rotating actuator (2) with a hollow output shaft controlling movement of an indicator with a light conducting path, connected to a light source, diffusing the light at an angle and a reduction gear set. The path has an outer diameter D between 2.6 and 5.5 millimeter and light source is arranged below the path. The ratio between inner diameter of the shaft and inner diameter of a bearing receiving the shaft is more than 0.9, where the inner surface of the shaft presents a high reflecting power. |
