Abstract: A vehicle lamp includes a light source mounted on a vehicle body and a light guide body for guiding light generated by the light source. On the light guide body, vertically to a light travelling direction, a plurality of notch-shaped portions are formed in line. The notch-shaped portions become narrow in pitch as the distance from the light source increases and are formed deeper as the distance from the light source increases. Preferably, the notch-shaped portions exhibit arc cross-sections having the same curvature radius, and the depths of the notch-shaped portions are specified by the central angles of the arc cross-sections.

Abstract: A display device on a meter panel of an automobile, indicates the following distance from a vehicle to a preceding vehicle by displaying multiple blocks, and recognition of the following distance is made easy thus preventing erroneous recognition. The display includes three blocks and three sub-blocks between a vehicle symbol and a preceding vehicle symbol. The three blocks can be switched between a display state and a non-display state and the three sub-blocks are constantly in a display state. The blocks and sub-blocks are positioned so as to correspond to each other. When all three blocks are in a display state, this denotes that the following distance is ‘long’, when two of the blocks are in a display state, it denotes that the following distance is ‘medium’ and when only one block is in a display state, it denotes that the following distance is ‘short’.
