Does anyone know where I am able to get projector headlights? I have recently purchased an HHR and wanting to do it up

 

Welcome to the site. As far as I know, there's no place that offers the projector style headlights for our cars. I remember reading about a site that would retro-fit them into a set of headlamps but it was around $1000 IIRC

 

This guy just retrofit a set from a BMW. May help you out:
