Lots of other guys here with more info and experience than me, but I'll give you my .02. Projectors or not, the electronics on the Ram 13+ are fairly complicated. You'd be better off spending a little more to get a proven solution. Just to read a little, I'd go to Retro....Solutions and read what they have there. Good reviews on these guys. they're good about responding to email questions too.
If you don't have projectors, then you should think about adjusting the lights after you upgrade. The standard reflectors have a lot of scatter.
