Deep imaging and longslit spectroscopy of two cold, embedded IRAS sources of intermediate luminosity, powering molecular outflows, shows that they are associated with bipolar reflection nebulae. The reflected light consists mainly of H emission with a broad P Cygni profile, as is typical for Herbig Ae/Be stars. The inferred wind velocities are 85 to 120 km s-1.
