What I would recommend are the Philips Vision Plus for H7.<br>

I can attest to their brightness. I bought them from a site in the UK and had them shipped to the States. (http://www.autolamps-online.com/halogen/index.htm)<br>
<br>
You cannot buy them outside of Europe, but this site has no problems sending them Stateside.<br>
<br>
Enjoy.<br>

Side note: one of the bulbs in your CL230 is a Philips (of the same series as the VisionPlus), the other is an OSRAM. Stock bulbs are bright, but these are about 20% brighter.<br>
