Automotive lamp (10), preferably a backup lamp, includes first lamp (12) and plural LEDs (26a-n). The lamp (12) comprises light-transmissive material, first and second opposed end surfaces (16, 18), a source side (20) and an emission side (22) each extending between end surfaces (16, 18), source side (20) facing LEDs (26a-n), and emission side (22) having an aspherical surface facing area to be illuminated (24). The elongated optical lens (14) has a length (L) extending, parallel a first horizontal X-axis, between the end surfaces (16, 18) that is greater than a thickness along second horizontal Z-axis and a height along vertical Y-axis (X-, Y-, and Z-axes being mutually orthogonal). Elongated optical lens (14) defines focus line segment (FS) extending parallel the X-axis, and preferably bends LED light below a horizontal XZ plane, i.e. back towards source side (20). Backup lamp (12) provides to camera (52) ground illumination of minimum 1 lux at distances 0-6 meter when mounted to vehicle at heights between conventional bumper and roofline.
