180° Half Hemispheres - for 3-way "T" intersections | 
90° Quarter Hemispheres - for 2-way "L" situations | |

T-Panoramic Safety Mirrors | 
Observation distance: up to 8 m. | The T Junction Panoramic safety mirror is equipped with a special wide-angle mirror, which gives a clear line of vision in both directions. The T-panoramic mirror is therefore particularly useful at T-junctions / intersections, where it replaces two conventional safety mirrors. The photo below was taken from the facing car. The driver overlooks both directions effectively. Because of the reduction of the image in the corners we recommend the T-panorama mirror only in places with slow driving traffic.
