The high beam low beam may not be so easy to accomplish....
Low beam turns off when high beam is activated, am I right?
Low beam supplies power to the ballast. When you pull high beam, the power from high beam light bulb should remain on the high beam light bulb, but also should power the solenoid opening the shield on the projector.
If the low beam gets deactivated, the projector light supply goes dark. To keep it going you can setup a small relay or a circuit that would provide current in either situation.
Unless the low beam stays on with high beam... I am not sure and too lazy to check myself.
However, a few years ago when I did full retrofit in 2009 Elantra, I left the high beam operational along with the projector.
Since then I loved driving this car at night on twisty roads. Man, it was like a daylight.
