There is a huge number of portable electronic devices like mobile phones on the market. In order to improve the visibility of a particular device, some manufactures have developed portable electronic devices that are carried visibly all times. But when it is dark or very crowded, it may be rather difficult for other persons to see and appreciate the design of a portable electronic device, or to even notice it. One reason for this is that the visibility of the portable electronic device is limited. So, the main idea is to improve the visibility of portable electronic devices. This can be achieved by connecting light guiding means in e.g. the carrying belt or carrying strap of the portable electronic device to light sources in the portable electronic device and allowing light to escape from the carrying means. There are small outlets in the carrying means from where light obtained from at least one light source escapes from the light guiding means. The effect of the light guiding means and the outlets is that the device can be seen from a greater distance away. If light sources in the device are activated, e.g. when it is used, the light carrying means are wholly or partly illuminated for some distance. E.g. an alerting mobile terminal can be recognized much more efficiently since the user observes light emitted on an area spanning a larger spatial angle. Instead of optical fibres, a planar waveguide such as the widely employed display backlights can be used. This would result a more uniform distribution of light but slightly reduce the flexibility of the carrying means.
