Abstract: The present invention provides a light source module for a vehicle comprising: a plate-like heat sink; substrates provided on both sides of the heat sink, respectively; light emitting devices provided on the substrates, respectively; a hole for transmitting light emitted from the light emitting devices; and a pair of bases coupled to the outside of the substrates, wherein the light emitting device includes a first light emitting device and a second light emitting device which are arranged diagonally, and a blocking member is disposed at a lower end of the second light emitting device. As such, it is possible to increase the heat dissipation efficiency by increasing the contact between the heat sink and the substrates.
