ORDER TELEGRAPHS; ALARM SYSTEMS ## Abstract A Display device gives a visual warning to a car driver who is turning off a main road into a side road about a person who is approaching the side road parallel to the main road, the display device includes at least one sensor for sensing the person and at least one light which emits a visual warning signal when a person approaches, wherein the emission angle of the light which emits the visual warning signal is oriented so as to open into the intersection region between a first axis running transversely with respect to the course of the main road and a second axis running transversely with respect to the course of the side road. ## Claims ### Claim 1 A display device for giving a visual warning to a car driver who is turning off a main road into a side road about a person who is approaching the side road parallel to the main road, comprising: at least one sensor for sensing the person and at least one light which emits a visual warning signal when a person approaches, wherein the emission angle of the light which emits the visual warning signal is oriented so as to open into the intersection region between a first axis running transversely with respect to the course of the main road and a second axis running transversely with respect to the course of the side road and wherein the emission angle of the light is limited by the first axis and the second axis. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the display device is at least partially formed as a railing accompanying the transition from the main road to the side road. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the at least one light is arranged at the height of a passenger car window. ### Claim 4 (depends on 1) The display device according to claim 1, wherein the at least one light is arranged at the height of a truck window. ### Claim 5 (depends on 1) The display device according to claim 1, wherein the at least one light is designed as a display. ### Claim 6 (depends on 1) The display device according to claim 1, wherein the at least one light is convex. ### Claim 7 (depends on 1) The display device according to claim 1, wherein the display device has a lighting device which at least partially illuminates the quadrants diagonally opposite the intersection region. ### Claim 8 (depends on 1) The display device according to claim 1 further comprising a photovoltaic system supplying the display device with energy. ### Claim 9 (depends on 1) The display device according to claim 1, wherein the person sensed by the display device is a cyclist. ### Claim 10 A display device for giving a visual warning to a car driver who is turning off a main road into a side road about a person who is approaching the side road parallel to the main road, comprising: at least one sensor for sensing the person; at least one light which emits a visual warning signal when a person approaches, wherein the emission angle of the light which emits the visual warning signal is oriented so as to open into the intersection region between a first axis running transversely with respect to the course of the main road and a second axis running transversely with respect to the course of the side road; and a lighting device which at least partially illuminates the quadrants diagonally opposite the intersection region. ### Claim 11 (depends on 10) The display device according to claim 10, wherein the display device is at least partially formed as a railing accompanying the transition from the main road to the side road. ### Claim 12 (depends on 10) The display device according to claim 10, wherein the at least one light is arranged at the height of a truck window. ### Claim 13 (depends on 10) The display device according to claim 10, wherein the at least one light is convex. ### Claim 14 (depends on 10) The display device according to claim 10 further comprising a photovoltaic system supplying the display device with energy. ### Claim 15 A display device for giving a visual warning to a car driver who is turning off a main road into a side road about a person who is approaching the side road parallel to the main road, comprising: at least one sensor for sensing the person; at least one light which emits a visual warning signal when a person approaches, wherein the emission angle of the light which emits the visual warning signal is oriented so as to open into the intersection region between a first axis running transversely with respect to the course of the main road and a second axis running transversely with respect to the course of the side road; and a photovoltaic system supplying the display device with energy. ### Claim 16 (depends on 15) The display device according to claim 15, wherein the display device is at least partially formed as a railing accompanying the transition from the main road to the side road. ### Claim 17 (depends on 15) The display device according to claim 15, wherein the at least one light is arranged at the height of a truck window. ### Claim 18 (depends on 15) The display device according to claim 15, wherein the at least one light is convex. ### Claim 19 (depends on 15) The display device according to claim 15, wherein the display device has a lighting device which at least partially illuminates the quadrants diagonally opposite the intersection region.
