I have done this before. the lamps just plug in and work.
You will not have HRA (auto aiming) like Gilly said, but the lamps
will work just dandy. The only draw back is an occasional "Check front lowbeam" message that may pop up in the cluster from time to time. Usually in cold weather.

DON'T FORGET to aim these darn things correctly and low, to avoid dazzling oncoming drivers.
