2000 Subaru Outback high Beam headlight replacement technique?
Start by removing the plastic protective cover by twisting to
the right and pulling off. The low beam light is a small halogen
light at the top of the two light clusters. The lower light is the
high beam light (part 9005 typically). The low beam light goes into
the light casing at the top under the funny dome like structure and
is reflected backwards onto the light casing to create the low
beam. It's a $12 part usually. One plug, one spring, no tools
required for drivers side, 10MM socket to remove airscoop intake on
passenger side in order to get to light cover.
