That little bulb is an accent light. The one above it is the high beam. High beams are typically inboard and low beams outer, at least that's my observation.
If you a ultrabright LED bulb in there I will personally come to your house and open your headlight with a grinder and remove it.![]()
Are you sure? My wife's '13 Outback had a similar light configuration, and the small light in the reflector is the daytime running light.
The light in the center of the reflector is the high beam, the projector light is low beam, and the amber light in the upper outer, is the marker/turn signal light.
