Upgrade my headlights
 

I would like to upgrade my "stock" sealed halogen beams. Definitely want to keep my DRL's I have read some of the posts and been to a couple of vendor sites and the confusion runs as deep and wide as a ocean.

I know the units are SB6545H. Before I call a site. It would be nice if the sites would offer a roadmap for the conversion (additional wire harness if required). I've done complex electrical retrofits in my occupation, but I do feel stymied now! Constructive advice very welcome.
