The difference is, with the crystals, when you flick the stalk to high beam, it activates the high beam and switches off the dipped. On the ph2 with single optics, it doesnt. So if your using a ph2 stalk on crystals, only difference is when you use your high beam, the dipped beam stays on.
You mean the phase 2 stalk and crystals (twin optic) activates either main or dipped but not both together
The phase 3 stalk with crystals (twin optic) activates both bulbes dipped and main at the same time
:p
