Can I replace the Litronic Headlight assembly with the cheaper non-Litronic assembly?

Can I replace the Litronic Headlight assembly with the cheaper non-Litronic assembly? The Litronic assembly has 2 electrical sockets and the non-Litronic has just the main socket. I have had some problems the driver side assembly coming loose and the main electrical socket is not seating properly. I went through the wheel well and by pushing down on the socket from the back and pushing in the headlight assembly, I was able to get it seated. But the assembly keeps coming loose after awhile, the lever does not seem to be putting enough tension on the assembly to keep it in place. Any ideas or suggestions? I have a 2003 Boxster s.
