The utility model provides a LED (light emitting diode) automobile signal lamp, includes base, lens plate, circuit board and lamp shade, and this circuit board is fixed in on the base and pastes and is equipped with the light source, and this lens plate is fixed in the light emitting area of circuit board, and this lamp shade cover is located lens plate and outer and link to each other with the base, be equipped with at least convex closure lens on this lens plate, vertical direction of these convex closure lens makes incident ray roll over the light -emitting light that constitutes narrow laser angle partially, and this horizontal direction is equipped with a plurality of convex closure portions so that incident ray rolls over the light -emitting light that constitutes wide laser angle in opposite directions partially. The utility model discloses can make the facula of convex closure lens be the fusiform, the facula of this shape can satisfy multiple car light rules (including back position lamp, brake light, rear steering lamp, reverse light etc. ), easily processing, with low costs, small with lower light source consumption.
