Abstract: The present invention relates to a LED lamp unit (10) comprising at least two LED light sources (2) arranged between a heat sink (3) and an electrical connector base at two opposing sides of the lamp unit (10) to emit in opposed half spaces. The proposed LED lamp unit can be constructed in a very compact form in order to replace known halogen, xenon and incandescent bulbs without changing the construction of the reflector and mechanical parts in a head lamp or signaling lamp.
