Light guide for use in an automotive environment, preferably as part of a turn signal indicator and/or a lamp for illuminating an area inside or outside a vehicle, and adapted to receive light from a light source, the light guide comprising: at least one elongated light guide element having, in cross section, a front surface for decoupling light from the light guide and a back surface having reflective properties, the front surface at least partially comprising a light decoupling area; and at least one connection element (8, 10) protruding, in said cross section, from an upper and/or lower surface of the light guide element for mechanically connecting the light guide to a receiving structure, wherein the connection element (8, 10) is located closer to the back surface of the light guide element than to the front surface and the back surface is at least partially convexly curved in said cross section, and wherein light is coupled out of the light guide through the front surface, and wherein over at least 30 % of the minimum length of the light guide element and over at least 30 % of the maximum height of the light guide element in cross section the following applies: 0.8 < B B / H L + B B / 10 * D L < 30, wherein B B = convex bending radius of the back surface of the light guide element in cross section; H L = maximum height of the light guide element perpendicular to a center line in cross section, where the center line is from the front surface to the back surface at half maximum height; and D L = maximum depth of the light guide element along the center line in cross section. at least one elongated light guide element having, in cross section, a front surface for decoupling light from the light guide and a back surface having reflective properties, the front surface at least partially comprising a light decoupling area; and at least one connection element (8, 10) protruding, in said cross section, from an upper and/or lower surface of the light guide element for mechanically connecting the light guide to a receiving structure, wherein the connection element (8, 10) is located closer to the back surface of the light guide element than to the front surface and the back surface is at least partially convexly curved in said cross section, and wherein light is coupled out of the light guide through the front surface, and wherein over at least 30 % of the minimum length of the light guide element and over at least 30 % of the maximum height of the light guide element in cross section the following applies: 0.8 < B B / H L + B B / 10 * D L < 30, wherein B B = convex bending radius of the back surface of the light guide element in cross section; H L = maximum height of the light guide element perpendicular to a center line in cross section, where the center line is from the front surface to the back surface at half maximum height; and D L = maximum depth of the light guide element along the center line in cross section. B B = convex bending radius of the back surface of the light guide element in cross section; H L = maximum height of the light guide element perpendicular to a center line in cross section, where the center line is from the front surface to the back surface at half maximum height; and D L = maximum depth of the light guide element along the center line in cross section.
