MY REXTC,
I wouldn't get the Diamond Vision IMHO, they definitely have decreased light output compared to the Crystal.
Philips have a new product called X-Treme power which gives 80% more light compared to standard globes, the only problem with those, is that they don't have the entire range of headlight globes yet. What type of bulbs are you after, as I have a catalog at work, and can tell you if they make them...
Below is a website which has some great information about headlight bulbs etc...
This article is specifically on Blue headlight globes, but it has heaps of other info, ie. HID's in non HID type headlight assemblies. (although since I fitted HID to my non HID high beams, I've been very happy!
)
