Need suggestions on how to deal with burnt out light fixture

[Steve S.]

In one of my more high end rentals, I'm dealing with a burnt out socket on one half of one of the 2 master bath light fixtures.

There are two fixtures with 2 lights each.

What would you recommend? I would assume I will need to replace both fixtures (all 4 lights) so they match and have an electrician do the install since that's not something I'm familiar with doing.

Any recommendations?  I haven't been able to match just the one fixture.

Not sure why it's showing up sideways or how to rotate it.  Doesn't appear crooked on my computer.
