Headlights, wich bulb to buy??

[elijah.vdp]

Hello my name is Elijah and I have a few questions as I know nothing about headlights and everything that goes with it. I have standard headlights on my 2006 X3 and wished I had gotten Xenon.
On jlevistreetwerks.com I see two different products with huge price differences.
1. D2S Xenon Bulb Set (Choose Color) 159$
2. Predator Xenix Bulbs 25$
Wich ones to get?
Im only looking to get a nicer look for my headlights, something blueish (like xenons) but with good visibility capabilities. Could you please recommend me the right products?

Also the Predator ThinLine X3 (Xenon Only), is it really impossible to install without the Xenons?

Thank you very much for your responses.
