I would like to swap out my high beams for some HID or Xenon lights, as they don't like favorable next to the factory HIDs. Any suggestions what brand to use or where to find the best lights? Thanks.

HID's don't really provide the instant-on that high beams need especially in flashing scenarios, not to mention you will really blind oncoming traffic if you accidentally leave them on. HID's also hate being hot-fired, so they hate being flashed. You're better off with some colored bulbs in the high-beams if it's all for looks. If you must though, you can find kits all over the internet for roughly 40-60 bucks.

Yea, my concern isn't that they have to be HID, I just hate that they are cream colored when the factory low beams are clear white. So what type of colored bulbs would be best to match the low beams on the clk.. white.. clear? Thanks.

Always had luck with Polarg Bi-Hybrid's
