Headlight ? help?

I have projector HID's . I upgraded from an older 325 to an 07 335i, I want 8000k HID,s.... Do I need to whole kit or just order xenon lights? Dunno if there are ballast already there . This may sound stupid but I must know ASAP! Lights aren't bright enough.. And will new ones make my angel eyes brighter ?
thanks !

If your car already has the bi-xenon (projector) headlights then all you need to do is replace the bulbs. Most people get this confused but the higher is kelvin you go, the less light output you get, not the other way around. The most popular choice among customers is 6k as it's the perfect balance between color and light output. A 6k bulb will give you a white color with a slight hint of blue. I'd recommend that you check out the GP Thunder D1S replacement HID bulbs.

The Angel eyes are separate from the low/high beam HID bulbs. The E92 coupes use an H8 bulb instead. I'd recommend you check out the 6W LED Angel eye bulbs by City Vision Lighting. The City Vision LED Angel Eyes feature a 6 watt 6000K pure white LED bulb for a brilliant white light that looks classy on any model BMW.

All you need is the bulb, but the above post is right, if want the bightness xenon, stay with oem or no higher than 6000K kelvin. Changes are, a 5 years old xenon bulb have lost some of its brightness, chances should increase the light output but there is a seperate bulb for your angle eyes, so the answer is no, changing the xenon will not make the angle eye brighter.
