We present I, Hα and [S II] CCD images of the dense cores L 1527 and L 1448. A diffuse reflection nebulosity is observed in L 1527. A red spectrum shows that superimposed on the reflection nebulosity there is HH emission of low excitation and very low radial velocity, υlsr ≍ 5.2 km s-1. The object is most probably excited by the very young Class O object IRAS 04368 $ 2557. The data suggest that the IRAS source is surrounded by a dense, flattened circumstellar envelope seen edge-on and approximately oriented in a NS direction. The HH emission and reflection nebula are located along the polar direction of this envelope. A reflection nebulosity and HH emission is also observed in L 1448. We suggest that they are associated with the Class O object L 1448N (IRAS 03225 + 3034). Our findings increase to four the number of Class O objects associated with HH emission, which represents ≍30% of the Class O sources known to date.
