Projection HID headlights

[ROX]

Okay, I've searched and found out there are two disctinct types of HID headlights.

Projection H.I.D. lights and replacement HID headlights. Both now come with hi/lo beam features.

My question is, which one works the best?

I've searched the internet and found that a lot of these places don't exactly give a definition of a Projection HID system.

My search on the H2Source has revealed the best description (of course) about Delta HID lights.

Could I get some feedback on these two different systems?

I tried the new bulb in the headlight assembly trick, and it just isn't doing any better. I'm thinking new lights all together will help. It gets very dark and rainy out here, and flipping on the PIAA's isn't exactly legal but MAN do they work good.
