Replace low beam head lamp

I replaced the low beam and high beam on my Subaru, now the low beam is very dim and the high beam doesn’t work. Careful not to touch the bulb. Any suggestions?

Sounds like a loose or dirty connection. Try unplugging the capsules, cleaning the harnesses, and plugging them back in.

What was the reason for replacing both in the first place?

The low beam burned out. Pulled the high beam out by mistake. The bulb broke on the high beam, so I replaced both.
