Abstract
The invention relates to a sighting device, containing an elongate light source (11) and an elongate body (15) made from a material which conducts light and/or collects light. The light source (11) and body (15) are disposed coaxially. A user looking into the device in the viewing direction (3) sees at least one luminous mark under all light conditions. In weak or failing ambient light, at least the light source (11) appears as a luminous dot and in strong ambient light, the face of the body (15) directed towards the user radiates collected light. In the transition range between weak and strong ambient light, both the light source (11) and the luminous face of the body (15) are visible to the user.
